Working Advice
General Information
The reception lens 11 and the laser beam outlet 12 must not
be covered when taking a measurement.
Measurement takes place at the center of the laser beam,
even when target surfaces are at a slope.
Influence Effects on the Measuring Range
The measuring range depends on the light conditions and the
reflection properties of the target surface.
Influence Effects on the Measuring Result
Due to physical effects, faulty measurements cannot be
excluded when measuring on different surfaces. Included
here are:
– Transparent surfaces (e.g., glass, water),
– Reflecting surfaces (e.g., polished metal, glass),
– Porous surfaces (e.g. insulation materials),
– Structured surfaces (e.g., roughcast, natural stone).
Also, air layers with varying temperatures or indirectly received
reflections can affect the measured value.
