,
and
adjust the laser so that
the vertical beam passes through point
a1
and on the wall, mark
the center of the cross beams as
a2
(see figure 4).
9) Measure the distances:
Δa= |
a2-a1
|
Δb= |
b1-b2
|
10) The difference | Δa – Δb| should be no more than 2 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
