Checking measurement precision
Check precision of the measuring instrument
– before starting work,
– after large temperature changes
– after violent impacts.
Before measuring angles up to 45°, check
the precision on a horizontal surface (~0°),
before measuring angles over 45°, vertical
surface (~90°).
The steps required to check the precision
are explained at the end of these instructions
on the illustrated pages.
See from page 180.
For deviations of >0.1° calibrate the measu-
ring instrument.
Calibration
See also from page 182.
– Position contact surface on a straight
surface which is as level as possible.
Mark position! Switch on device and press
the REF button until CAL 1 flashes.
Shortly afterwards an acoustic signal
sounds and CAL 2 is displayed.
– Now turn the spirit level horizontally by 180°
and place exactly on the marked area
(reversal measurement).
Press the REF button again until CAL 2
flashes. The following acoustic signal
ends the process.
Concluding test: The device is correctly
calibrated when the same measured values
are displayed in both positions (0° and 180°).
If the precision deviates from the permitted
tolerance range, the device must be taken
to a customer service workshop authorised
by the manufacturer.
Have the device adjusted by authorised
technicians only.
