Cause
Battery indicator decreasing
Battery voltage decreasing (measurement still
possible).
Battery indicator empty, measurement not possible
Battery voltage too low
"ERROR" indication 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 8 or the reception lens 9
are misted up (e.g. due to a rapid temperature
change).
Calculated value is larger than 9 999 999 or
2
smaller than – 999 999 m/m /m
The calibration of the grade measurement was
not carried out in the correct sequence or in the
correct positions.
The surfaces used for calibration were not pre-
cisely horizontal.
The measuring tool was moved or tilted while
pressing the button.
