Press and hold the measuring button 2. When the cur-
sor is on the desired setting, release the measuring
button 2. After releasing, the measuring tool switches
itself on with the selected setting.
Display Illumination
The display illumination is continuously switched on. When no button is pressed, the
display illumination is dimmed after approx. 10 seconds to preserve the batteries/re-
chargeable batteries. When no button is pressed for after approx. 30 seconds, the
display illumination goes out.
Working Advice
General Information
The reception lens 7 and the laser beam outlet 8 must not be covered when taking a
measurement.
The measuring tool must not be moved while taking a measurement. Therefore, place
the measuring tool, as far as this is possible, against or on a firm stop or supporting
surface.
Influence Effects on the Measuring Range
The measuring range depends on the lighting conditions and the reflective properties
of the target surface. For better visibility of the laser beam in extraneous light, use the
laser viewing glasses 10 (accessories) and the laser target plate 9 (accessories) or
shade the target area.
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 9 (accessory) on these surfaces.
Furthermore, faulty measurements are also possible when sighting inclined target
surfaces.
Also, air layers with varying temperatures or indirectly received reflections can affect
the measured value.
