Field Calibration Check

CHECKING ACCURACY – HORIZONTAL BEAM, SCAN
DIRECTION (FIG. 5)
Checking the horizontal scan calibration of the laser requires two walls
30' (9 m) 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 its pivot bracket, with the laser
facing straight ahead toward the opposing wall (0 degree
position).
2. Turn on the laser's horizontal beam and mark the beam position
on the opposing wall directly across from the laser. Always mark
the center of the beam's thickness.
3. Pivot the laser to the extreme left (–90 degree position) and mark
the beam position on the opposing wall.
4. Pivot the laser to the extreme right (+90 degree position) and
mark the beam position on the opposing wall.
5. Measure the vertical distance between the lowest mark (A)
and the highest mark (B). If the measurement is greater than
the values shown in Table 1, the laser must be serviced at an
authorized service center.

CHECKING ACCURACY – HORIZONTAL BEAM, PITCH
DIRECTION (FIG. 6)
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.
