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 ± 2 mm. Repeat the process by
turning the laser to the left.

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 ± 2 mm.
Regularly check the calibration before use, after transport and
after extended periods of storage.
