Battery indication a is indicated
Battery voltage decreasing
(measurement still possible)
Battery indication a flashes, measurement not
possible
Battery voltage too low
The indications "ERROR" and "–––––" are
indicated 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 19 or
the reception lens 20 are
misted up (e.g. due to a
rapid temperature change).
