Cause
"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 16 or
the reception lens 17 are
misted up (e.g. due to a rapid
temperature change).
Calculated value is greater
than 99999 m/m
"Error" indication flashes at in display (top)
Addition/Subtraction of
measured values with
different units of measure
Unreliable measuring result
The target surface does not
reflect correctly (e.g. water,
glass).
The laser beam outlet 16
or the reception lens 17 are
covered.
Measuring result not plausible
Wrong reference level set
Obstruction in path of laser
beam
an error, have the measuring tool checked by an after-sales
service agent for Bosch power tools.

/m .
The measuring tool monitors the correct func-
tion for each measurement. When a defect is
determined, only the symbol shown aside flash-
es in the display. In this case, or when the above
mentioned corrective measures cannot correct
Corrective Measure
Enlargen the angle between
the laser beam and the target
Work with the laser target
plate 20 (accessory)
Wipe the laser beam outlet 16
and/or the reception lens 17
dry using a soft cloth
Divide calculation into inter-
mediate steps
Only add/subtract measured
values with the same units of
measure
Cover off the target surface
Make sure that the laser
beam outlet 16 or the recep-
tion lens 17 are unobstructed
Select reference level that
corresponds to measurement
Laser point must be com-
pletely on target surface.
