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.
