The deviation of the individual measurements from the mean value must not exceed
±2 mm (max.). Log the measurements, so that you can compare their accuracy at a
later point of time.
Measuring with Positioning Plate (see figure B)
Using the positioning plate 3 is suitable for applications such as measuring from a cor-
ner (room diagonal) or from hard-to-reach areas.
Fold out the positioning plate 3.
Set the reference level to measurement with positioning plate in the measuring tool.
When the measurement has been completed, fold the positioning plate 3 back in.
Troubleshooting – Causes and Corrective Measures
Cause
Temperature warning indicator (b) flashing; measurement not possible
The measuring tool is outside the operating tem-
perature range from – 10 °C to + 50 °C (in the
continuous measurement function up to
+40 °C).
Battery indicator decreasing
Battery voltage decreasing (measurement still
possible).
Battery indicator empty, measurement not possible
Battery voltage too low
"ERROR" indication in the display
The angle between the laser beam and the target
is too acute.
The target surface reflects too intensely (e.g. a
mirror) or insufficiently (e.g. black fabric), or the
ambient light is too bright.
The laser beam outlet 8 or the reception lens 9
are misted up (e.g. due to a rapid temperature
change).
Calculated value is greater than 999 999 or
2
smaller than –999 999 m/m /m
