*maximum deviation occurs under unfavourable conditions such as bright sunlight or when measuring to poorly reflecting or very rough surfaces. Measuring accuracy may deteriorate by approx.
± 0.1 mm/m for distances above 30 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
Aiming at high gloss surfaces may deflect the laser beam and lead to measurement errors.
