Technical data
* 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.
Measuring conditions
Measuring range
The range is limited to 200 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 reflection 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 measu-
rement errors.
Against non-reflective and dark surfaces the measuring time may increase.
