Horizontal Line Accuracy - Tilt
Checking the tilt of the laser's horizontal line requires a flat
vertical surface at least 9m (30') wide.
Place a tripod as shown in Figure
1.
• At the center of the wall (D 1/2).
• In front of the wall at a distance of half the size of the wall
(D 1/2).
Place the laser on a tripod and screw the threaded knob on
