Working Advice
General Information
The reception lens 12 and the laser beam outlet 13 must not be covered when taking
a measurement.
The measuring tool must not be moved while taking a measurement (with the excep-
tion of the continuous measurement function). Therefore, place the measuring tool,
as far as this is possible, against or on the measuring points.
Measurement takes place at the centre of the laser beam, even when target surfaces
are sighted at an incline.
Influence Effects on the Measuring Range
The measuring range depends upon the light conditions and the reflection properties
of the target surface. For improved visibility of the laser beam when working outdoors
and when the sunlight is intense, use the laser viewing glasses 15 (accessory) and the
laser target plate 16 (accessory), or shade off 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).
If required, use the laser target plate 16 (accessory) on these surfaces.
Also, air layers with varying temperatures or indirectly received reflections can affect
the measured value.
Troubleshooting – Causes and Corrective Measures

ment still possible).
