Laser Distance Meter DM 100
The distance that can be measured is limited to 50 metres.
At dusk or at night, if the target is in shade, the distance
that can be measured without using a target plate is
increased.
Use a target plate to increase the distance that can be
measured in daylight or if the measurement zone has poor
optical reflection properties.
Measurement
errors
measurements made in the direction of transparent liquids
(such as water), glass that is free of impurities,
polystyrene, or similar semipermeable materials. Aiming at
varnished surfaces may deflect the laser beam and lead to
measurement
measurement may increase if the device is aimed at non-
reflecting or black surfaces.
Do not immerse the device in water. To remove dust from
the optical part, use a damp soft cloth. For the housing,
use soapy water, not aggressive cleaning agents. The
precautions to be taken are the same as for any optical
instrument (telescope, camera, etc.).
