General Information
The reception lens 15 and the laser beam outlet 16
must not be covered when taking a measurement.
The laser measure must not be moved while taking a
measurement. Therefore, place the laser measure, as
much as possible, against or on a firm stop or support-
ing surface.
Influence on the Measuring Range
The measuring range depends on the light conditions
and the reflection properties of the target surface.
Influence on the Measuring Result
Due to physical effects, faulty measurements cannot
be excluded when measuring on different surfaces
which include:
– Transparent surfaces (e.g., glass, water),
– Reflecting surfaces (e.g., polished metal, glass),
– Porous surfaces (e.g. insulation materials),
– Structured
stone).
Also, air layers with varying temperatures or indirectly
received reflections can affect the measured value.

ment. Hold down the function button 2 [Func]. Press
