Checking Accuracy – Horizontal Beam, Pitch Direction (Fig. G)
Checking the horizontal pitch calibration of the laser requires a single wall at least 30' (9 m) long. It is important to conduct a
calibration check using a distance no shorter than the distance of the applications for which the tool will be used.
1. Attach the laser to one end of a wall using its pivot bracket.
2. Turn on the laser's horizontal beam and pivot the laser toward the opposite end of the wall and approximately parallel to the
adjacent wall.
3. Mark the center of the beam at two locations (a, b) at least 30' (9m) apart.
4. Reposition the laser to the opposite end of the wall.
5. Turn on the laser's horizontal beam and pivot the laser back toward the
first end of the wall and approximately parallel to the adjacent wall.
6. Adjust the height of the laser so that the center of the beam is aligned
with the nearest mark (b).
7. Mark the center of the beam (c) directly above or below the farthest
mark (a).
8. Measure the distance between these two marks (a, c).
• If the measurement is greater than the values shown below, the laser
must be serviced at an authorized service center.
