Working with the Tripod (Accessory)
The use of a tripod is particularly necessary for
larger distances. Position the measuring tool
with the 1/4" thread 17 onto the quick-change
plate of the tripod 23 or a commercially available
camera tripod. Tighten the measuring tool with
the locking screw of the quick-change plate.
Set the corresponding reference level for meas-
urement with a tripod by pushing button 1 (the
reference level is the thread).
Troubleshooting
Corrective Measures
Cause
Temperature warning indicator (c) flashing;
measurement not possible
The measuring tool is not
within the operating tem-
perature range of –10 °C
to +50°C; for continuous
measurements (functions
minimum/maximum
measurement) to +40 °C.
Battery low indicator (b) appears
Battery voltage decreas-
ing (measurement still
possible)
Battery low indicator (b) flashing; measure-
ment not possible
Battery voltage too low

Cause
"Error" and "––––" indication in display
The angle between the la-
ser beam and the target is
too acute.
The target surface reflects
too intensely (e.g. a mir-
ror) or insufficiently (e.g.
black fabric), or the ambi-
ent light is too bright.
The laser beam outlet 21
or the reception lens 22
are misted up (e.g. due to
a rapid temperature
change).
