Performing the calibration check:
3. Position the device as near as possible to the wall at the height
of point A1.
4. Turn the device through 180° and mark point A3.
The difference between points A2 and A3 is the tolerance.

Checking the vertical line:
Position the device about 5 m from a wall. Fix a plumb bob with a line of
2.5 m length on the wall, making sure that the bob can swing freely. Switch
on the device and align the vertical laser to the plumb line. The precision
is within the specified tolerance if the deviation between the laser line and
the plumb line is not greater than ± 1 mm.
Checking the horizontal line:
Position the device about 5 m from a wall and
switch on the cross laser. Mark point B on the wall.
Turn the laser cross approx. 2.5 m to the right and
mark point C. Check whether the horizontal line
from point C is level with point B to within ± 1 mm. Repeat the process by
turning the laser to the left.
!
Regularly check the adjustment before use, after transport and after
extended periods of storage.
