Sighting with the Alingment Aid (see figure E)
With the alignment aid 7, 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.
Working with the Tripod (see figure C)
The use of a tripod is particularly necessary for larger distanc-
es. Position the measuring tool with the 1/4" thread 14 onto
the quick-change plate of the tripod 20 or a commercially
available camera tripod. Tighten the measuring tool with the
locking screw of the quick-change plate.
When positioning the tripod, observe that the measurement
will take place beginning from the rear or front edge of the
measuring tool, depending on the selected reference level.
Troubleshooting Causes and Corrective Meas-
–
ures
Cause
Temperature warning indicator (b) flashing; measure-
ment 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 (a) appears
Battery voltage decreasing (meas-
urement still possible)
Battery low indicator (a) flashing; measurement not pos-
sible
Battery voltage too low
"Error" and "––––" indication in display
The angle between the laser beam
and the target is too acute.
The target surface reflects too in-
tensely (e.g. a mirror) or insuffi-
ciently (e.g. black fabric), or the
ambient light is too bright.
The laser beam outlet 18 or the re-
ception lens 19 are misted up
(e.g. due to a rapid temperature
change).
