8.2 Laser
1. Make a marking (a, b)
2. Mark point c
3. Turn the laser spirit level
upside-down and mark point d
4. Mark the middle point between points c
and d. Then position the adjusting card.
The arrow (line M) must point to the
middle point you marked previously.
Points c and d must be in the green
tolerance range. If not, return the laser
spirit level to your dealer.
8.3. Inclination module
Testing the calibration:
To prevent faulty measurements we recommend testing the calibration each time before use. This
especially after shocks, significant temperature changes or long periods of storage.
Alternate horizontal test:
Place the inclination spirit level on a hard surface which is
as horizontal as possible and look at the LCD. Switch on
the inclination gauge on using the Q button and after 10
seconds note the value it displays. Then turn it around on
the same surface by 180°. Wait 10 seconds and compare
the two values. If the difference between the two values is
more than 0.1°, then it must be horizontally recalibrated.
