Indicators for Checking Calibration
(Calibration Warning)
If the calibration of the measuring tool has
to be checked, this is shown on the display
of the laser receiver after switching on by
means of various indicators in combination
with the "CAL" indicator.
Note: The sensors for a calibration warning
(calibration interval, storage temperature,
shocks to the measuring tool are active after
the tool is started up for the first time.

Cause
/
The calibration interval
(every 12 months) has
expired.
The measuring tool
/
was stored outside
of the storage
temperature range.
The measuring tool
suffered a severe
shock (e.g. impact on
the floor after a fall).
until the cause of the calibration
warning occurs again.
Recommended procedure after an
indication to check calibration
Step
1 Check leveling accuracy
2a Deviation is within the
maximum permitted limits of
±1/16-in (±1.5 mm):
Switch off calibration warning
indicators
2b Deviation is outside of the
maximum permitted limits of
±1/16-in (±1.5 mm):
Calibrate measuring tool
3
Check leveling accuracy
4a Deviation after calibration is
within the maximum permitted
limits of ±1/16-in (±1.5 mm):
Work can be performed
without loss of accuracy.
4b Deviation after calibration is
still outside of the maximum
permitted limits of ±1/16-in
(±1.5 mm):
Have measuring tool checked
by a Bosch customer service
agent
