Accuracy Checking
NOTE: Due to the complicated, sensitive nature of these procedures, ordinarily only a qualified technician would attempt them.
Level Beam Accuracy
1.Set up the instrument with the Tripod centered between two walls approximately 16 ft. apart. Please ensure the Rotary Base is level.
2.Press both the horizontal and vertical buttons to project a laser cross on wall A. Mark point a1 at the intersection of the beams. Turn the cross line laser 180° and repeat on wall B, marking point b1 at the intersection of the beams, see below.
3.Move the instrument straight towards wall A to a point 2 ft. away and repeat step 2, marking the intersections as a2 and b2, see below.
4.a distance (da)=a1
If da - db <1mm, the accuracy is within tolerance. Otherwise, return the instrument to a qualified technician for repair.
Horizontal Beam Level Accuracy
(End to End)
1.Set up the instrument with the Tripod approximately 16 ft. from the wall. Please ensure the Rotary Base is level.
2.Press both the horizontal and vertical buttons to project a laser cross on the wall, mark point a 8 ft. from the intersection of the beams to the right on the horizontal beam.
3.Turn the instrument until the vertical beam has moved 16 ft. to the right side, and mark b 8 ft. from the intersection of
