* 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.
Measuring conditions
Measuring range
The range is limited to 100 m.
At night or dusk and if the target is in shadow the
measuring range without target plate is increased.
Use a target plate to increase the measurement
range during daylight or if the target has poor reflec-
tion properties.
Target surfaces
Measuring errors can occur when measuring toward
colourless liquids (e.g. water) or dust free glass,
Styrofoam or similar semi-permeable surfaces.
Aiming at high gloss surfaces may deflect the laser
beam and lead to measurement errors.
Against non-reflective and dark surfaces the
measuring time may increase.
