Indirect measurement
The instrument can calculate distances using Pythagoras’ theorem.
Two different distances (a and b) can be entered into the instrument and
can then be used to mark off defined measured lengths, e.g. in the const-
ruction of wooden frames.
This procedure is helpful, if the distance to measure can not be reached
directly.

All target points must be in a horizontal or vertical plane.
The best results are achieved when the instrument is rotated about a
fixed point (e.g. with the positioning bracket fully folded out and the
instrument placed on a wall) or the DISTO™ is mounted on a tripod.
The minimum/maximum function can be used - see explanation in

Double tilt measurement with one measured distance
This procedure is particularly helpful if one target point of those to be
measured cannot be reflective. The second target point can be simply
pointed at with the digital viewfinder. In this measurement it is the angle
only and not the distance that is measured and therefore no special target

Operation
Tilt measurements:
* maximum deviation occurs under unfavourable conditions such as bright sunlight or
when measuring to poorly reflecting or very rough surfaces. Measuring accuracy
between 10 m and 30 m may deteriorate to approx. ± 0.025 mm/m, for distances
above 30 m to ± 0.1 mm/m. In long range mode the maximum deviation from a
distance of 30 m increases to +/- 0.15 mm/m.
** applies at room temperature. For the whole operating temperature range the
maximum deviation increases by +/- 0.1°.

water) or dust free glass, Styrofoam or similar semi-permeable surfaces.

Do not immerse the instrument in water. Wipe off dirt with a damp, soft
cloth. Do not use aggressive cleaning agents or solutions. Handle the inst-
