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 ± 1.5 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 ± 3 mm. Repeat the process by turning the
laser to the left.
!
Regularly check the calibration before use, after transport and after extended
periods of storage.
