2. Check the leveling accuracy of the horizontal beam.
3. Check the leveling accuracy of the vertical beam.
4. Check the perpendicularity between the 2 vertical beams.
1. Checking the Height Accuracy of the Horizontal beam.
(Up and down deviation)
1) Set up the laser on a tripod or on a flat surface between two
walls A and B, approximately 5 meters apart.
2) Position the laser level at approximately 0.5 meters from wall A
3) Unlock the pendulum safety lock (#11), to project the forward
horizontal and the vertical cross beams towards wall A.
4) Mark the center of the cross beams on the wall as a1
(see figure # 1).
