Working Advice

6.1

General Information

The reception lens 7 and the laser beam outlet 8 must
not be covered when taking a measurement.
Measurement takes place at the centre of the laser
beam, even when target surfaces are sighted at an in-
cline.
6.2 Influence Effects on the Measuring
Range
The measuring range depends on the light conditions
and the reflection properties of the target surface.
6.3 Influence Effects on the Measuring
Result
Due to physical effects, faulty measurements cannot be
excluded when measuring on different surfaces. Includ-
ed 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.
