Influence Effects on the Measuring Result
Due to physical effects, faulty measurements cannot be exclud-
ed 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 20 (accessory) on these
surfaces.
Also, air layers with varying temperatures or indirectly received
reflections can affect the measured value.
Sighting with the Alingment Aid (see figure D)
With the alignment aid 8, sighting over larger distances is a lot
easier. For this, look alongside the aligning aid on the top side
of the measuring tool. The laser beam runs parallel to this line
of sight.
Troubleshooting
Cause
Temperature warning indicator (c) flashing; measurement
not possible
The measuring tool is outside
the operating temperature
range from – 10 °C to + 50 °C
(in the function continuous
measurement up to +40 °C).
Battery low indicator (b) appears
Battery voltage decreasing
(measurement still possible)
Battery low indicator (b) flashing; measurement not possible
Battery voltage too low
