Aligning with the Spirit Level
The spirit level 16 allows for simple levelling of the measuring
tool. This allows for easier sighting of target surfaces, especially
over longer distances.
In combination with the laser beam, the spirit level 16 is not
suitable for levelling.
Sighting with the Alingment Aid (see figure G)
With the alignment aid 11, 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
"Error" and "––––" indication in 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 19 or
the reception lens 20 are
misted up (e.g. due to a rapid
temperature change).
