8. Turn the laser 180° towards wall
A,
and mark on the
wall the center of the cross beams as
a2
(see figure 4).
9. Measure the distances:
Δ
a=
|a2-a1|
Δ
b=
|b1-b2|
10.The difference |
Δ
a –
Δ
b| should be no more than
3 mm,if otherwise send the laser level to a qualified
technician for repair.
2. Checking the Level Accuracy of the Horizontal beam.
(Side to side inclination)
1. Set up the laser on a tripod or on a flat surface at a
distance of approximately 1.5 meters from a 5 meter/
16 feet long wall.
2. Unlock the pendulum and press the button to project the
