8. Measuring conditions
Measuring distance
The laser meter has a range of up to 50 m.
Measurements over greater distances can also be carried out under cer-
tain conditions, for example at night, dusk, when the target is shaded
without having to use a target plate. A target plate can be used during the
day to increase the measuring distance if the target itself exhibits poor
reflective characteristics.
Target surfaces
Errors may occur during measuring if the laser beam is directed at unco-
loured liquids (e.g. water), glass that is free of dust, polystyrene or other
semi-permeable materials. Further errors may also occur when the laser
beam is deflected from surfaces which have strong reflective properties.
Matt, non-reflecting surfaces can result in longer measuring times.
Cleaning
Do not immerse the laser into water. Clean with a damp cloth only. Do not
use caustic cleaning agents. Treat your laser distance meter in exactly
the same way you would normally treat an expensive camera or any
other piece of sensitive equipment.
