Field Calibration Check
CHECKING ACCURACY – HORIZONTAL BEAM, SCAN DIRECTION (FIG. 6)
Checking the horizontal scan calibration of the laser requires two walls 30’ (9m) apart. 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 a wall using a pivot bracket. Make sure the laser is facing straight ahead.
2. Turn on the laser’s beams and pivot the laser approximately 45˚ so that the right-most end of the laser line is striking the opposing wall at a distance of at
least 30’ (9m). Mark the center of the beam (a).
3. Pivot the laser approximately 90˚ to bring the left-most end of the laser line around to the mark made in Step 2. Mark the center of the beam (b).
4. Measure the vertical distance between the marks.
5. If the measurement is greater than the values shown below, the laser must be serviced at an authorized service center.

CHECKING ACCURACY – HORIZONTAL BEAM, PITCH DIRECTION (FIG. 7)
When checking the horizontal beam 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. Mount the laser on a tripod as close as possible to a wall at distance D1. (Wall #1)
2. Turn on the laser and project the horizontal beam onto the nearest wall. (Wall #1)
3. Mark the center of the beam at Point P1.
4. Rotate the laser 180
°
and mark the center of the beam on the opposing wall (Wall #2) at Point P2.
5. Reposition the laser close to the opposite wall (Wall #2) at distance D1.
6. Turn on the laser and project the horizontal beam onto Wall #2
7. Adjust the height of the laser so that the center of the beam is aligned with Point P2.
8. Rotate the laser 180
°
and mark the center of the beam on the opposing wall (Wall #1) at Point P3.
9. Measure the distance between thesepoints P1 and P3.
10. If the measurement is greater than the values shown below, the laser must be serviced at an authorized service center.
