 COSMO 100
* In favourable conditions (good target surface properties, room temperature).
Maximum deviation occurs under unfavorable conditions such as bright sunlight or when measuring to
poorly reflecting or very rough surfaces.
Measuring conditions
Measuring range: the range is limited to 100 m. At night, at dusk and when the target is shadowed the
measuring range without target plate is increased. Use a target plate to increase the measurement range
during daylight or if the target has a bad reflection.
Measuring Surfaces
Measuring errors can occur when measuring toward colorless liquids (e.g. water) or dust free glass, styro-
foam or similar semi-permeable surfaces. Aiming at high gloss surfaces deflects the laser beam and mea-
surement errors can occur. Against non-reflective and dark surfaces the measuring time can be increased.
