6. Locating Buried Cables And Pipes  
A. Transmitter Connections  
Perform a battery test. Use one of the following three methods to produce a trace signal  
on the target pipe or cable.  
1. Direct Connect Method  
! WARNING  
This WARNING applies to the use of the Direct Connect Cables and the Transmitter.  
To avoid potential shock, or electrically damaging the Transmitter, when setting up the  
Transmitter to locate using the Direct Connect method, follow these basic steps;  
ALWAYS plug the Direct Connect Cable into the Transmitter Output Jack [T-6] BEFORE  
connecting the leads to the cable/pipe to be located and the ground rod.  
– Connect the red lead to the cable/pipe.  
– Connect the black lead to ground rod.  
A POTENTIAL FOR ELECTRICAL SHOCK, AND/OR TRANSMITTER ELECTRICAL DAMAGE, EXISTS  
WHEN USING THE DIRECT CONNECT CABLE ON CABLES ENERGIZED WITH ELECTRICAL POWER  
IF THE ABOVE INSTRUCTIONS ARE NOT FOLLOWED. USE APPROPRIATE SAFETY PROCEDURES.  
CHECK VOLTAGE BEFORE CONNECTING TRANSMITTER. VOLTAGE HIGHER THAN 240 VOLTS WILL  
DAMAGE EQUIPMENT. FOLLOW STANDARD PROCEDURES FOR REDUCING THE VOLTAGE.  
Plug the direct connect cable into the Output Jack [T-6] of the transmitter. Connect  
the black clip to the ground rod. Place the ground rod in the earth perpendicular to  
the suspected cable/pipe path. If necessary, extend the black lead with the Ground  
Extension Cable (#9043 available separately).  
Remove the ground bonding and attach the red clip to the shield of the cable, pipe,  
or target conductor. (If locating power cables, the red clip can be attached to the  
transformer cabinet, or the meter box). Metal contact must be made between the red  
clip and the transformer cabinet or meter box. If painted, some paint will need to be  
removed/scraped off to allow metal-to-metal contact.  
Turn the transmitter on by pressing Ohms [T-2]. The continuity of the circuit will be  
measured. The results are displayed on the Digital Display [T-4] in ohms and as an  
audible tone.  
78-9000-0192-2 Rev C  
21  
Download from Www.Somanuals.com. All Manuals Search And Download.  
If the continuity of the circuit is very good (the reading on the display is less than  
3K Ω. and a solid tone from the transmitter is heard) all frequencies can be used to  
locate. Always use the lowest frequency available (for example, 577 Hz). Lower  
frequencies are less likely to ‘bleed over’ to other cables in the same area, and are  
very good for tracing over long distances.  
− If the circuit reads more than 3K Ω., but less than lOK Ω (indicated by a beeping  
tone from the transmitter) it will be necessary to use a higher frequency than  
577 Hz in order to locate the cable/pipe.  
− If the circuit reads more than lOK Ω., it will be necessary to use an RF signal such  
as 33 kHz, 82 kHz or 200 kHz.  
If there is no tone and the transmitter indicates that there is an open circuit (OL  
in the display) this could be an indication of a poor ground, or an open-ended  
cable or pipe. Use one of the higher frequencies available, at high or maximum  
output power level. If it is an open-ended cable or pipe, the receiver's response will  
decrease suddenly at the site of the clear or severed end.  
Note: In the ohms mode, the transmitter can detect voltage as well as ohms. If a low  
voltage is detected, the Digital Display [T-4] will alternate between displaying ohms  
and volts. When displaying ohms, the flag over the symbol will be visible. When  
displaying volts, the flag over the ‘V' will be visible. When the voltage magnitude  
is sufficient to impair the accuracy of the ohms measurement, only voltage will be  
displayed. If the voltage is AC, a sine wave will be visible on the Digital Display [T-4].  
If a high AC voltage is detected, a rapid beeping tone will be heard.  
Press Trace [T-3] repeatedly until the desired frequency appears on the display. Note  
that the number that flashes alternately with the selected frequency is called the  
relative current. This number can be useful in identifying the target cable/pipe and  
is discussed more in 8. Depth and Current Estimate and 10. Locating in Directional  
Peak Mode.  
Press Output Level [T-5] to select high, or maximum, output power level for longer  
tracing distances or deep pipe/cable.

2. 3M™ Dyna-Coupler Method  
! WARNING  
This WARNING applies to the following 3M Dyna-Couplers;  
• 3" (75 mm) - Part number 3001  
• 4.5" (114 mm) - Part number 4001  
• 6" (150 mm) - Part number 1196  
• All accessory kits containing any of the listed Dyna-Couplers - Part numbers 3019, 4519,  
1196/C  
A potential for electrical shock exists when using the Dyna-Coupler on cables energized with  
electrical power. Use appropriate safety procedures.  
DO NOT USE ON CABLES CARRYING IN EXCESS OF 600 VOLTS RMS.  
Use a ground extension cable,  
or wire, and ground rod set-up  
between a target pipe/cable and  
a gas meter valve/box, or cable/  
electrical meter box. This will isolate  
the locate signal to the target pipe/  
cable section below the meter/box,  
between the grounding points. This  
provides a good return path for the  
tracing signal. Insulating coupling  
above a gas meter valve on a pipe  
will isolate the returning signal from  
ground and may make locating  
more difficult.  
Connect the Dyna-Coupler to the transmitter Output Jack [T-6] using the coupler  
cable (9011).  
Clamp the Dyna-Coupler around the cable or pipe, below any bonds, just before it  
enters the earth. The jaws of the coupler must fully close.  
Press Trace [T-3] to turn on the transmitter. Press again to select 8 kHz, 33 kHz,  
82 kHz or 200 kHz.  
Note: When using a Dyna-Coupler, always select high, or maximum, output power  
level by pressing Output Level [T-5] key on the transmitter.

3. Induction Method  
If you cannot make a direct connection, or use the 3MDyna-Coupler clamp to apply a  
locating signal on the target, use the induction method. When nothing is plugged into the  
Output Jack [T-6] of the transmitter the unit will be placed into induction mode when it  
is turned on. This method uses the internal coil of the transmitter to generate a magnetic  
field. This is the least preferred method of applying a signal on a target conductor  
because it can easily be picked up by other non-target conductors in the area. However,  
it is the preferred method of applying a signal to multiple cables/pipes in the same trench  
and for the “two-person sweeping” application.  
3M Dynateltransmitters provide a choice of induction frequencies and output power  
levels. Higher induction output power levels are needed for detecting deeper depths  
and longer ranges. The 2500 Series transmitters provide four induction frequencies:  
8 kHz, 33 kHz, 82 kHz and 200 kHz and three output power settings up to 12W. The  
82 kHz and 200 kHz frequencies are commonly used for deeper cables/pipes and the  
lower frequencies are used to give longer locate distances. The 8 kHz (low frequency)  
induction helps in locating shallow facilities, such as risers.  
The following sections review Non-sweeping and Sweeping (Area) methods used  
with the Induction Mode. The Non-Sweeping method is utilized when a specific target  
requires path tracing. The transmitter remains stationary in-line over the target and the  
path is traced. The Sweeping method is utilized when a designated area needs to be  
swept for non-specific targets, for example, all the buried pipes or conductors in the  
designated area. Several sweeping methods will be reviewed.  
A. Non-Sweeping(Passive) Induction Mode Locating  
Position the transmitter over the target facility, with the hinge of the transmitter over  
and in line with the cable/pipe path. Remove any cables from the Output Jack [T-6].  
Align the Induction Direction arrows on the transmitter with the target conductor.  
Turn on the transmitter, select the frequency and select high output or maximum  
output power level for best signal-to-noise ratio.  
Trace the signal path with the receiver using the Induction Peak (Ind Pk) mode.  
The Induction Peak (Ind Pk) mode of the receiver is a mode in which the upper antenna  
of the receiver is tuned to minimize distortion from the magnetic field of the transmitter.  
Use Induction Peak (Ind Pk) mode when sweeping distance between the transmitter and  
receiver is 25–60 feet (7.6–20 m). Beyond 60 feet (20 m) you can also use the Special  
(single) Peak (Spl Pk) or Directional Peak (Dir Pk) modes. Special (single) Peak (Spl  
Pk) can be used for maximum detection depth and range (needed for deep conductors  
and metal pipes), but would require increased sweep distance separation between the  
transmitter and receiver.  
24  
78-9000-0192-2 Rev C  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Note: If nothing is plugged into the Output Jack [T-6] of the transmitter, the  
transmitter will automatically turn on the internal antennae, and the last frequency  
used (8 kHz, 33 kHz, 82 kHz or 200 kHz) will broadcast in induction mode.  
The induction frequency can be changed by pressing the Trace [T-3] (Frequency [T-3]  
on 2550) button on the transmitter. For best results, the receiver should be at least 25  
feet (7.6 m) away from the transmitter to begin tracing the target path, have the gain  
set between 78-84% and have the receiver in Induction Peak (Ind Pk) mode when  
starting the sweep. Attempting to trace the target close to the transmitter may lead to  
false indications due to the receiver detecting the large magnetic field radiating from  
the transmitter.  
B. Sweeping (Active) Induction Mode Locating  
Sweeping an area with the 3MDynatelLocator 2500 Series allows the location of  
multiple metallic cables and pipes buried in an area without direct connect or coupler  
access to the cable or pipe. This approach is effective before any excavation takes place.  
Note that when specific buried objects need to be identified, it's important to use the  
direct connect or coupler method for applying the signal. This will help limit the applied  
locate signal to a specific facility that provides more position and depth accuracy along  
with an effective identification. There are two main types of “no access” or “blind”  
Induction Sweeps;  
Passive Sweeps: These require only the use of the Receiver with passive frequency  
detection capability. This method uses existing external signal sources, such as 60 Hz/50  
Hz for electric power, 15 kHz to approximately 30 kHz for low frequency radio signals,  
120 Hz / 100 Hz CPS for impressed current Cathodic Protection signals and the less  
commonly occurring CATV signal of 31.25 kHz NTSC with CRT TV turned on.  
Active Sweeps: These require both the Receiver and Transmitter with Induction  
capability. This method refers to using a 3M Dynatel transmitter as the signal source  
through induction, instead of relying on passive frequencies that may exist on the  
buried conductor or metal pipe. Active Induction allows for detecting buried cables  
and metal pipes in the absence of passive signals and at deep depths and short sections.  
3M Dynatel transmitters provide a choice of induction frequencies and output power  
levels. Higher induction output power levels are needed for detecting deeper depths  
and longer ranges. The 2500 Series transmitters provide four induction frequencies: 8  
kHz, 33 kHz, 82 kHz and 200 kHz and three output power settings up to 12W. The 82  
kHz and 200 kHz frequencies are commonly used for deeper cables/pipes and the lower  
frequencies are used to give longer locate distances.  
C. Passive Sweeps  
Select Special (single) Peak (Spl Pk) mode on the receiver and then select the frequency  
(source; for example, power, LF, etc.) to be traced. Passive sweeps at power frequency  
will detect buried power cables and conductors carrying 60 Hz/50 Hz power signal in the  
ground. Other passive sources exist, such as Cathodic Protection, LF and CATV cable  
(with NTSC TV CRT turned on).

Walk in a grid pattern over the sweep area holding the receiver as shown in the  
following illustration. Stop when there is a response increase, locate the position of the  
maximum signal, follow the conductor path all the way out of the sweep area while  
putting location marks on the ground. Resume the sweep until another cable or pipe is  
detected, or the whole area is completely swept. Switch to another available passive  
frequency in the receiver and sweep again.  
D. One-person Active Induction Mode Sweeps  
One-person active induction mode sweeps require that the transmitter be set on the  
ground over the suspected path of the buried infrastructure. The receiver is used to  
detect signals induced by the transmitter on buried long conductors. Proper placement  
and orientation is key to maximize the induced signal in the buried cable or metallic  
pipe enough to be detectable by the receiver along each path in the swept area. (Note  
that no signal is induced onto a conductor whose path is perpendicular to the Induction  
Direction indication.)  
Place the transmitter in the upright (bottom on ground) position for directional  
optimization when aligned with the Induction Direction shown on the label on the  
transmitter.  
Tip the transmitter over towards the front, and lay it on it's front surface, for multi-  
directional wide area induction. (Note that no signal is induced onto a conductor  
whose path is directly under the transmitter).  
Remove anything plugged into the Output Jack [T-6] (this will place unit in Induction  
Mode), select highest available frequency (200 kHz) and highest output power level.  
Select the Induction Peak (Ind Pk) mode and 200 kHz frequency on the receiver.  
When in close proximity to the transmitter in induction mode, there is a direct signal  
from the induction antenna in the transmitter to the receiver through the air. Induction  
Peak (Ind Pk) mode is a newly added locate mode for use in closer proximity to a  
transmitter in Induction mode (<60 ft , 20 m typ.). Special (single) Peak (Spl Pk)  
would give the highest sensitivity, but is affected by the air signal more than Induction  
Peak (Ind Pk) mode.

E. Two-person Active Induction Mode Sweeps  
In two-person active induction mode sweeps, one person holds the transmitter and  
the other holds the receiver while walking together in a sweep pattern detecting long  
conductors in the ground when crossed by transmitter and receiver positions and  
orientation, as shown below:  
Transmitter Set-up  
Remove anything plugged into the Output Jack [T-6] (this will place unit in Induction  
Mode), select high frequency (200 kHz), or medium frequency (33 kHz or 82 kHz),  
and highest output power level.  
Hold the transmitter with the lid facing up and align it with the Induction Direction  
arrow label, as shown on the transmitter, with the receiver  
Receiver Set-up  
Set the receiver to the same frequency as the transmitter.  
Select the Induction Peak (Ind Pk) mode, and press the Gain [3] (+ or -) key until the  
Bar Graph [11] ([10] for 2550) is just visible.  
Sweeping  
Sweeping can be done at close distances between the transmitter and receiver.  
For best results, the receiver should be at least 25 feet (7.6 m) away from the  
transmitter to begin tracing the target path and have the gain set between 78-84%  
when starting the sweep. Attempting to trace the target close to the transmitter may  
lead to false indications due to the receiver detecting the large magnetic field radiating  
from the transmitter.  
Induction Peak (Ind Pk) mode cancels the air signal coming directly from the  
transmitter induction antenna to the receiver. Increasing the sweep distance between  
the transmitter and receiver reduces the direct air signal and allows for sensing deeper  
conductors and sections of metal pipes. Use Induction Peak (Ind Pk) mode when  
sweeping distance between the transmitter and receiver is 25–60 feet (7.6–20 m).  
Beyond 60 feet (20 m) you can also use the Trace View (T-view), Special (single)  
Peak (Spl Pk) or Directional Peak (Dir Pk) modes.  
Special (single) Peak (Spl Pk) can be used for maximum detection depth and range  
(needed for deep conductors and metal pipes), but would require increased sweep  
distance separation between the transmitter and receiver.

7. Receiver Locating Trace Modes  
A. Trace View (T-View)  
TRACE [2]  
Trace View mode, or T-View, provides an intuitive mapping display showing the utility  
path utilizing a dynamic directional arrows and path indication line. This combination  
provides an excellent visual representation of the utility path and directional assistance  
to assist in pinpointing the target.  
Several displays may be seen when using Trace View:  
Display 1. When the receiver is outside of the detectable locating signal range, the  
display will show a solid circle inside of a dotted circle. At times it may  
show the dynamic directional arrow shown in Display 2 and/or the image  
in Display 4 below. The images may flash alternately indicating that the  
receiver is out of detectable locating signal range. See following example;  
Display 2. When the receiver is within the detectable locating signal on the target, a  
steady target line will appear on the receiver display representing the target.  
The dynamic directional display arrows will guide the operator towards the  
target. The receiver volume and the signal strength increase as the target is  
approached. See following examples;

Display 3. As the receiver antenna crosses the target, the receiver volume increases to  
a maximum, the signal strength will be at its maximum and the directional  
arrow will become a straight line that is closely lined up with the target line  
on the display. See following examples;  
On Target Path  
Display 4. A circle consisting of two arrows appears when the orientation of the receiver  
is not at the optimum position in relation to the target. The arrows indicate  
that the receiver should be twisted to obtain the optimum position. See  
following examples;  
Twist Receiver  
B. Special Peak (Spl Pk)  
TRACE [2] + Mode [SK] + Spl Pk [SK Toggle] or  
Menu/OK [5] + Cable/Pipe [SK] + Mode [SK] + Spl Pk [SK Toggle]  
Special Peak mode turns on only the peak antenna closest to the ground. Special Peak  
Mode is used in applications such as very deep cables or pipes, or when the signal is too  
weak for Directional Peak (Dir Pk) or Trace View (T-View) mode tracing.

If you cannot make a direct connection, or use the 3MDyna-Coupler clamp to apply  
a locating signal on the target, use the induction method. This method uses the internal  
coil of the transmitter to generate a magnetic field.

D. Directional Peak (Dir Pk)  
TRACE [2] + Mode [SK] + Dir Pk [SK Toggle]  
or Menu/OK [5] + Cable/Pipe [SK] + Mode [SK] + Dir Pk [SK Toggle]  
In Directional Peak mode, four peak antennas are used to analyze the magnetic field  
pattern. The bar graph indicates signal strength and the directional arrows sense the  
edges of the magnetic field. The left/right arrows will indicate the direction to the nearest  
cable/pipe that is in-line with the receiver handle.  
As the antenna crosses the cable or pipe, the receiver speaker volume increases to a  
maximum, the Bar Graph [1l] ([10] for 2550 locator) fills from both sides toward the  
middle, and the numeric Signal Strength [9] ([8] for 2550 locator) increases. As the  
antenna moves off the target path, the speaker volume decreases and the Bar Graph [1l]  
([10] for 2550 locator) opens. Use the Bar Graph [1l] ([10] for 2550 locator) and the  
numeric Signal Strength [9] ([8] for 2550 locator) to locate the exact target path.  
Left of Target Path  
Directly Over Target Path  
Right of Target Path  
Once the target path has been located, the arrows at the top of the display will indicate  
the location of the target path in relationship to the receiver handle.  
Note: When field distortion (due to congestion) is affecting the receiver, the left/right  
arrows may not coincide with the bar graph. Use the maximum numerical Signal  
Strength [9] ([8] for 2550 locator) to target the cable or pipe.

E. Directional Null (DirNull)  
TRACE [2] + Mode [SK] + DirNull [SK Toggle]  
or Menu/OK [5] + Cable/Pipe [SK] + Mode [SK] + DirNull [SK Toggle]  
In Directional Null mode, as the operator approaches the cable or pipe, the numerical  
Signal Strength [9] ([8] for 2550 locator) will increase then fall sharply as the receiver  
crosses the target cable or pipe. The Bar Graph [11] ([10] for 2550 locator) fills from  
both sides toward the middle and the receiver speaker volume decreases. As the antenna  
moves off the target path, the Bar Graph [11] ([10] for 2550 locator) opens, the Signal  
Strength [9] ([8] for 2550 locator) increases, and the speaker volume increases. Gain  
adjust is automatic in Directional Null mode.  
The center of the DirNull display provides a ‘compass view' of the target path. An arrow  
will point toward the location of the cable/pipe in 45-degree steps. A solid line will  
appear over the cable/pipe, indicating its orientation to the receiver handle.  
For example:  
Figure 1: If the target path is to the right of the  
receiver, and running parallel to the operator, the  
right arrow will display.  
Figure 2: If the target path is to the left and in front  
of the operator (not running parallel to the receiver)  
the arrow will point toward the top left side of  
the display.  
Figure 3: When the receiver crosses the target path,  
a solid line will appear, instead of arrows, indicating  
the target path and its orientation to the receiver  
handle.  
Before marking target path, always use Directional Peak (Dir Pk), Special Peak (Spl Pk)  
or Trace View (T-View) mode to verify location.

When the third ring of the speaker icon is dotted  
or broken and ‘xpnd’ appears below the speaker  
icon as shown, the receiver is in “Expanded”  
mode. This mode is used for pinpointing a  
target cable or pipe. The area of response of the  
receiver narrows, allowing the locator to detect  
very small signal changes. Press the Speaker  
Volume Control [13] ([12] for 2550 locator) key  
to activate the "Expanded" mode.  
8. Depth and Current Estimate  
Verifying the target path, depth and current can be helpful tools.  
Pinpoint the cable or pipe being located.  
Lower the tip of the receiver to the ground and  
press DEPTH [4].  
The depth to the target cable or pipe is displayed  
in the units specified in the receiver set up  
menu. The bold current reading is the relative  
current measurement. This reading can be  
compared to the relative current reading that  
alternately flashes with the frequency on the  
transmitter to help identify the target cable/pipe.  
The highest relative current value will be the  
target cable/pipe and will compare closest to the  
transmitter relative current value. The milliamp  
reading is an actual current measurement.  
There are two options for measuring depth.  
Live depth is a continuous measurement. 1-Shot  
Depth is an averaging of the depth reading over  
a short period of time. When in 1-Shot mode,  
the unit will average the depth reading for three  
seconds, and then display the result on the  
display. Press DEPTH [4] to alternate between  
the two modes.  
Five depth readings can be saved with the time,  
date and relative current measurements.  
Pressing Mem Select [SK] and then Save [SK] will place each entry in sequential  
order in memory (M1–M5) until five readings have been stored. The unit will  
overwrite saved entries in excess of five, beginning with M1.

8k, 33k, 82k or 200k)  
Press Menu/OK [5] to return to Locate mode.  
B. Power Frequencies  
Power frequencies refer to 50 or 60 Hz signals, and their harmonics, that can be traced  
without the use of a transmitter.  
60: Best for general locating of passive power.  
60H (high harmonic): If the 60 choice appears to be responding slowly, or poorly, then  
60H is the second choice for locating passive power.  
60L (low harmonic): Third choice for passive power locating. May be used when 60 or  
60H is weak or erratic. 60L may be the best choice when locating primary power cables.  
120 Hz: Used for locating rectified AC power signals, often found on pipelines using  
impressed current cathodic protection.  
Press Menu/OK [5] (you may have to press Menu/OK [5] twice to toggle to the

10. Locating in Directional Peak Mode  
The following are instructions for locating a buried pipe or cable using the direct connect  
method and the Directional Peak (Dir Pk) mode. Other methods of connection and  
tracing modes/features are explained in previous sections.  
Step 1. Insert the ground rod into the ground, perpendicular to the suspected target  
path.  
Step 2. Remove the grounding from the near-end of the target cable/pipe.  
Note: Never connect or disconnect the transmitter when the unit is on.  
Step 3. Connect the red lead of the transmitter to the shield, neutral, or deenergized  
target conductor.  
Step 4. Connect the black lead of the transmitter to the ground rod.  
Step 5. Perform a battery check by pressing and holding off [T-1].  
Step 6. Power on the transmitter by pressing on [T-2] once. This will place the  
transmitter in Ohm-meter mode. An Indicator Flag will be displayed above the  
ohm symbol, , in the Digital Display [T-4].  
a. A solid tone from the transmitter indicates a complete circuit with a good  
ground.  
b. A beeping tone from the transmitter indicates a usable ground. An attempt  
should be made to improve the ground.  
c. No tone from the transmitter indicates a poor, or no ground. The transmitter  
will display ‘OL’ in this instance. An attempt should be made to improve the  
ground. Verify that the far end is grounded.  
Step 7. Press on Trace (Frequency on 2550 locator) [T-3] to set the transmitter to Trace  
mode.  
Step 8. Select a frequency on the transmitter by pressing Trace (Frequency on 2550  
locator) [T-3]. The unit will cycle through the available frequencies (577, 1K,  
8K, 33K, 82K, 200K and ALL).  
Step 9. Press On/Off [1] to power on the receiver.  
Step 10. Press Menu/OK [5] (you may have to press Menu/OK [5] twice to toggle to the  
LOCATE MENU display).  
Step 11. Press Cable/Pipe [SK].  
78-9000-0192-2 Rev C

Step 12. Set the Frequency and Mode of the receiver.  
a. Press Freq [SK]  
b. Select the same frequency on the  
receiver that was selected on the  
transmitter by pressing Active [SK  
Toggle].  
c. Press Menu/OK [5] to save the setting  
and return to Locate mode.  
d. Press Mode [SK Toggle] until Dir Pk is  
displayed.  
Step 13. Stand away from the suspected target path and adjust the Gain [3] down until  
the Bar Graph [11] ([10] for 2550 locator) opens completely.  
Step 14. Walk in a wide circle with your back toward the transmitter (about 10 to 15 feet  
(3 to 4.5 m) away).  
Watch the receiver display and listen to the signal. Take note of where the  
receiver detects the strongest Signal Strength [9] ([8] for 2550 locator).  
The Bar Graph [11] ([10] for 2550 locator) will close when the unit detects  
a signal, and the arrows will reverse.  
Adjust the Gain [3] down if the Bar Graph [11] ([10] for 2550 locator)  
closes completely.  
The Signal Strength [9] ([8] for 2550 locator) numbers on the display will  
change with the signal strength (smaller, as you walk away from the target  
path; larger, as you approach the target path).  
Make a complete circle around the transmitter. Return to each point in the  
circle that the receiver detected.  
Step 15. Measure the Depth and Current of each point to identify the target path. The  
depth of the target path should be as expected and the relative current should  
compare to the relative current that is alternately flashing with the frequency  
value on the transmitter.  
Note: The Relative Current reading will decrease steadily as the locator moves away  
from the transmitter. When using higher frequencies, this decline is more evident.  
Step 16. Adjust the gain so that the Bar Graph [11] ([10] for 2550 locator) responds to  
the target path (open when off path, almost completely closed when directly  
over target).  
Step 17. Trace the cable/pipe at a slow walk while moving the receiver in a side-to-side  
motion, keeping the receiver perpendicular to the ground.

Step 18. Measure the Depth and Current occasionally to verify target path.  
Note: In order to measure the Depth and Relative Current accurately, the operator  
must pinpoint the target pipe or cable, and the receiver handle should be in-line with  
the target path.  
While in Dir Pk mode, find the highest Signal Strength [9] ([8] for 2550  
locator).  
Lower the tip of the receiver to the ground. Twist the receiver left and right  
while watching the Signal Strength [9] ([8] for 2550 locator).  
When the highest reading is displayed, the handle of the unit is in line with  
the target pipe or cable.  
Occasionally a signal will appear on adjacent cables or pipes. Compare the  
relative and actual current readings (value that is under the relative current  
value and in mA units) over each path to help determine the target path. Current  
readings will be significantly less on the adjacent cable/pipe compared to the  
target path.  
Step 19. As tracing proceeds, remember that the most powerful signal is near the  
transmitter. As the receiver gets farther away from the transmitter the Signal  
Strength [9] ([8] for 2550) decreases. It may be necessary to readjust the gain  
as needed to be sure there is adequate signal for the receiver to operate. Press  
the Gain [3] up or down when the Bar Graph [11] ([10] for 2550 locator) is  
no longer visible (too little signal) or when the Bar Graph [11] ([10] for 2550  
locator) is closed (too much signal).  
Step 20. Trace the path until you reach a logical termination point (i.e.: terminal, meter,  
cabinet, etc).  
11. Locating Active Duct Probes (Sondes)  
Step 1. Press On/Off [1] on the receiver.  
Step 2. Press Menu/OK [5] (you may have to press Menu/OK [5] twice to toggle to the  
LOCATE MENU display).  
Step 3. Press Cable/Pipe [SK].  
Step 4. Press Mode [SK Toggle] to select Special Peak (Spl Pk).  
Step 5. Press Freq [SK].  
Step 6. Press Active [SK Toggle] to select the 33kHz frequency (for a 33 kHz Sonde  
or ADP (Active Duct Probe)).  
Step 7. Press Menu/OK [5].  
78-9000-0192-2 Rev C  
37  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Step 8. With the receiver handle perpendicular to the conduit path, locate the ADP  
position by moving along the path until the strongest Signal Strength [9] ([8]  
for 2550 locator) is found. Adjust Gain [3] up or down when the Bar Graph  
[11] ([10] for 2550 locator) remains either fully open or fully closed.  
Step 9. Refer to the ADP operating instructions for further information.  
A. Determining Active Duct Probe Depth  
Step 1. Place the tip of the receiver on the ground directly above the located ADP  
position.  
Step 2. Maintain the handle orientation perpendicular to the target path.  
Step 3. Press DEPTH [4].  
Step 4. Press Sonde Depth [SK] to read ADP Depth.  
The depth to the ADP is displayed in  
units as specified in the receiver set up  
menu.  
Five Sonde depth readings can be saved  
with the time and date measured. Press  
Mem Select [SK] after the Sonde depth  
displays.  
Press Mem Select [SK] to select a  
specific memory location (M1–M5) or  
select Save [SK]. Save [SK] will place  
each entry in sequential order in memory  
(M1–M5) until five readings have been  
stored. The unit will overwrite saved  
entries in excess of five, beginning  
with M1.  
Step 5. Optional step: Press Clear All [SK] to delete all saved depth readings.  
Step 6. Press Mem Select [SK] to select a specific memory location (M1 - M5) to store  
the depth readings.  
Step 7. When the preferred location appears on the display, press Save [SK]. The  
display and memory location will populate with the current information.  
Step 8. Each memory location can be reviewed by pressing Mem Select [SK].  
Step 9. Press Cable Depth [SK] to switch to the cable depth display, or Menu/OK [5] to  
return to Locate Mode.

12. Locating Buried Sheath Faults And Earth  
Return Faults  
(3MDynatelModels 2573 and 2573-iD only)  
Note: Remove (disconnect) both the near-end and far-end grounding from the test  
section.  
A. Transmitter Setup  
Note: Do not make any connections while the transmitter is on. Fault location will not  
work unless the near-end and far-end grounds are disconnected.  
Note: This method only works on direct buried cables/conductors. It will not work if  
the cables/conductors are faulted inside of a conduit, such as a PVC conduit.  
Step 1. Attach the red clip to the earth-faulted conductor of the cable or conductor  
under test.  
Step 2. Place the ground rod behind the transmitter and in parallel with the target path.  
Step 3. Connect the black clip to the ground rod behind the transmitter.  
Step 4. Press and hold On/Off [1] to perform a battery test.  
Step 5. Press on [T-2] once to power on the transmitter. This will place the transmitter  
in Ohm-meter mode. An Indicator Flag will be displayed above the ohm  
symbol, , in the Digital Display [T-4].  
The resistance of the fault will be displayed in ohms on the transmitter  
Digital Display [T-4].  
− Resistance less than 50KΩ = Significant fault exists  
− Resistance 50KΩ to 1.0MΩ = High resistance fault exists (May or may not  
cause problems yet, but gets worse with time.)  
− Resistance greater than 1.0MΩ = No significant fault exists  
Note: The fault locating limit is 2.0M, although the transmitter's ohm-meter mode  
can display a fault resistance up to 10M.  
Step 6. Press on [T-2] again, to select Fault mode.  
An Indicator Flag will be displayed above the fault locating symbol in the  
Digital Display [T-4]. (as shown in the illustration below)

B. Pinpointing the Buried Fault  
Step 1. Connect the 3MEarth Contact Frame to the External Jack [15] ([14] for 2550) of  
the receiver using the Earth Contact Frame cable (4 ft. (1.2 m) cable).  
Step 2. Press On/Off [1] to power on the receiver. The receiver display screen will  
display "Fauly Calibrating" for about 5 seconds.  
Step 3. Press Menu/OK [5].  
Step 4. Press Fault [SK] to select Fault mode.  
Step 5. Hold the receiver in one hand and the Earth Contact Frame in the other with the  
solid green-banded leg of the frame toward the test section. Near the location  
of the ground rod (about one Earth Contact Frame width away from the ground  
rod, slightly to the side and towards the faulted cable.), insert the Earth Contact  
Frame probes fully into the ground in line with the target path.  
Step 6. Press REF [SK] to record the fault Signal Strength [9] ([8] for 2550 locator)  
level reference. The signal level will be recorded in the box above REF [SK]  
on the display. This reference indicates the Signal Strength [9] ([8]) for 2550  
locator) level at the ground rod. When the operator reaches the major fault  
location, the Signal Strength [9] ([8]) for 2550 locator) indicated on the receiver  
will be very close (within 12dB) to this reference signal strength level.  
Step 7. Continue along the cable path, re-inserting the Earth Contact Frame probes  
every few steps while watching the receiver bar graph. The bar graph on the  
receiver will fill toward the right side of the display (green Fault Finding  
Direction Indicator [8] (See illustration below)), indicating that the fault is  
ahead of the operator (in the direction of the green-banded leg of the Earth  
Contact Frame).

Step 8. When the bar graph fills toward the left (red-and-white-striped Fault Finding  
Direction Indicator [8] (See illustration above.)) side of the display, the fault  
has been passed and is now behind the operator. Move back, inserting the  
3MEarth Contact Frame every few inches, until the arrows alternate back to  
green. Mark the point beneath the center of the Earth Contact Frame. Turn the  
Earth Contact Frame 90 degrees and insert into the ground over the previously  
marked point. Move the Earth Contact Frame to the left and right (following  
the directions of the green and red indicator arrows). When the arrows reverse a  
third time, turn the Earth Contact Frame 90 degrees again. Pinpoint the fault by  
moving the Earth Contact Frame in the direction of the green and red indicator  
arrows. The fault is located beneath the center of the Earth Contact Frame when  
the arrows change from one side to the other this time.  
Step 9. To verify the fault location, insert the Earth Contact Frame’s red-and-white-  
striped probe directly on the spot identified above. Pivot the Earth Contact  
Frame in a circle around the red-and-white-striped leg re-inserting the green-  
banded leg in the ground every few degrees of the circle (See figure below).  
The arrow should always point toward the left (red) indicating that the fault is  
directly below the red-and-white-striped leg.  
Step 10. After a fault is located and pinpointed, move the Earth Contact Frame about  
one Earth Contact Frame width away from the fault and insert it in the ground  
with the green-banded leg towards the fault. Compare the numeric signal  
level with the fault signal strength level reference indicated in the lower left  
box labeled REF. If the reading is within 12 dB of the fault signal strength  
reference, the operator has found the major fault. If the fault reading does not  
fall within 12 db of the fault signal strength reference reading, multiple faults  
may exist. The signal level of this secondary fault can be saved by pressing  
Fault 1 [SK] or Fault 2 [SK]. The fault with the highest reading will be the  
primary fault.

Menu/OK [5:Toggle to MAIN MENU] +  
[SK:3] + NMEA  
If the GPS device is not configured properly, there is an error communicating with the  
receiver, or the GPS device has not acquired enough satellites to pinpoint the location,  
the receiver will display the message “Insert External Device”.  
When the receiver is communicating with a GPS  
device, the LAT and LONG coordinates received  
from the device will appear on the marker locate  
display.  
Step 1. Locate a marker (See 13.C. Single Marker Locate)  
Step 2. Press Read [SK]  
The information from the 3MiD marker, as well as the GPS coordinates, will display  
on the receiver display. This information is saved automatically in the Read Marker  
History. (See 17. Reviewing Marker Read/Write History.)  
If the marker is a passive marker (rather than iD) the receiver will display “No iD  
Marker Found”. The GPS coordinates of the attempt to read the non-iD marker are  
stored in the Read Marker History as serial number # 0000-0000-0000. The marker  
details will indicate “not an iD marker”, but will display the GPS coordinates.

B. Sending 3MiD Marker Data to GPS  
(Capture-Transmit Mode / Mode 2)  
Menu/OK [5:Toggle to MAIN MENU] +  
[SK:3] + GIS  
Receivers that have marker locating capability (indicated by ‘iD’ in the model number)  
can be configured to send 3MiD Marker data directly to some GPS devices. When  
an iD marker is located and read, the information read from the iD marker with feature  
and attribute data is sent to the GPS device and is stamped with latitude, longitude and  
date/time data. The data acquired during this logging process can be uploaded to GIS  
mapping software. For more information and detailed instructions pertaining to specific  
GPS devices, refer to www.3M.com/dynatel for GPS instruction sheet.  
C. Path Mapping with GPS  
The 3M DynatelCable and Pipe Locators 2500 Series are compatible with hand-  
held GPS devices and now have the ability to map the path of underground target  
facilities. While measuring the depth to the target, the technician can automatically log  
the coordinates of the path to the GPS device. These logged points contain the Trace  
template that can have valuable information regarding the facility (owner, utility, size,  
etc.) and the method used to find the path (frequency, current, and measured depth).  
In order to transmit the path information to a GPS device, the GPS device has to have  
the ability to accept information on one of its com ports at 4800 Baud. Using the manual  
supplied with the GPS device, configure the com port of the GPS device to communicate  
with the receiver.  
If ArcPadsoftwae is the mapping software on the mobile device, download the 3M  
software application script from the website: www.3M.com/dynatel.  
With ArcPadapplication installed, the receiver will send the path information (locate  
frequency, depth, current, and trace template information) into the software program as a  
logged point and can be saved as a .shp file.

Up to four Trace Templates can be stored on the Receiver.  
Each Trace template is limited to 132 user editable characters.  
The trace template appears in table format: two columns with six lines.  
The first column is limited to 8 characters and the second column is limited to 14  
characters. In addition to the 132 character table, the receiver will send a sequence number,  
the frequency, the measured depth of the conductor, and the current to the GPS device.  
2. Select Com Port Setting  
Menu/OK [5:Toggle to MAIN MENU] +  
[SK:3] + GIS [SK] (or PDA [SK])  
If the GPS device has the ability to send NMEA coordinates on its com port and has the  
ability to receive information at 4800 baud, set the receiver’s com port to GIS.  
If the GPS device only has the ability to receive information, set the com port of the  
receiver to PDA mode.  
Log Prompt = On: Before the receiver returns to locate mode, a verification display  
will pop up on the receiver with the trace template information that will be sent to the  
GPS device. This information can be modified and confirmed. Press Menu/OK [5] to  
send to GPS device.  
Log Prompt = Off: When the receiver returns to locate mode, the trace template and  
locate information will be sent automatically to the GPS device.
