Indirect measurement
By using Pythagoras’ theorem, the instrument can calculate distances. This
function is helpful, if the distance to measure can not be reached directly.
Make sure you adhere to the prescribed sequence of measurement:
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 instrument is mounted on a tripod.
The minimum / maximum function can be used. The minimum value must be
used for measurements at right angles to the target; the maximum distance
for all other measurements.

** Maximum deviation occurs under unfavorable conditions such as bright sunlight or when measuring to poor
reflecting or very rough surfaces. For distances over 80m –without using a target plate –the maximum deviation
may increase to a maximum of ±10mm.
*** This is the typical value. For the limiting conditions (e.g. limiting temperature), the deviation increases a little.

17
Measuring conditions
Measuring range
As for the measure range limit, please refer to the technical specification.
At night, at dusk and when the target is shadowed the measuring range
without target plate is increased.
Use a target plate to increase the measurement range during daylight or if
the target has a bad reflection.
Measuring Surfaces
Measuring errors can occur when measuring toward colorless liquids (e.g.
water) or dust free glass, styrofoam or similar semi-permeable surfaces.
Aiming at high gloss surfaces deflects the laser beam and measurement
errors can occur.
Against non-reflective and dark surfaces the measuring time can be
increased.
Care
Do not immerse the unit in water. Wipe off dirt with a damp, soft cloth. Do
not use aggressive cleaning agents or solutions. Treat the optical surfaces
with the same care that you would apply to eyeglasses and cameras.
