4. Check the accuracy of the plumb line.
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 stable surface
between two walls A and B , approximately 5meters/16
feet apart.
2. Position the laser level approximately 0.5 meter from
wall
A.
3. Unlock the pendulum and press the button to project the
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).
