Calibration

The digital spirit level has been calibrated in the factory for maxi-
mum accuracy. If necessary, the digital spirit level can be re-
calibrated.
1. Switch off the digital spirit level. Place it on a flat and level sur-
face. Then switch on the spirit level again.
2. Simultaneously press the On/Off key (9) and the Hold/Sound key
(8) to enter calibration mode. Press the On/Off key. A few se-
conds later the number "-1-" flashes on the display.
3. Keep the digital spirit level unmoved until the number "-2-"
appears on the display. Horizontally flip over the digital spirit level
by 180°.
4. Press the On/Off key once more. A few seconds later the number
"-2-" is flashing on the display for a short time. Keep the digital
spirit level unmoved until the display returns to display the current
measuring value. The calibration process is finished.
Notes:
 The calibration must be performed on a flat and smooth surface
with a gradient lower than 5°.
 During calibration the digital spirit level must not be bevelled or
moved.
