Accuracy Check and
Calibration
NOTE:
• The laser tools are sealed and calibrated at the
factory to the accuracies specified.
• It is recommended to perform a calibration check
prior to its first use and then periodically during
future use.
• The laser tool should be checked regularly to ensure
its accuracies, especially for precise layouts.
• When performing the accuracy checks, use the
largest area / distance possible, closest to the
operating distance. The greater the area / distance,
the easier to measure the accuracy of the laser.
• The lock must be in the unlocked position to allow
the laser tool to self-level before checking the
accuracy.
CHECKING ACCURACY – HORIZONTAL BEAM,
SCAN DIRECTION (FIG. E)
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 or
mount on a tripod close to the wall, with the laser
facing straight ahead toward the opposing wall
(0 degree position).
2.
Turn on the laser's horizontal beam and side
vertical beam, 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 -90 degree to the left of center and
mark the beam position (a) on the opposing wall.
4.
Pivot the laser +90 degrees to the right of center
and mark the beam position (b) 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
below, the laser must be serviced at an authorized
service center.

CHECKING ACCURACY – HORIZONTAL BEAM,
PITCH DIRECTION (FIG. F)
Checking the horizontal pitch calibration of the
laser requires a single wall at least 30' (9m) 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 a pivot
bracket or mount on tripod close to the wall
with the laser facing straight ahead toward the
opposing wall (0 degree position).
2.
Turn on the laser's horizontal beam and project the
laser toward the opposite wall and approximately
parallel to the adjacent wall.
3.
Mark the center of the beam at two locations (c, d)
at least 30' (9m) apart.
4.
Reposition the laser to the opposite wall with the
laser facing straight ahead toward the first wall
(0 degree position).
5.
Turn on the laser's horizontal beam and pivot the
laser back toward the first 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 (d).
7.
Mark the center of the beam (e) directly above or
below the farthest mark (c).
8.
Measure the distance between these two marks
(c, e). If the measurement is greater than the values
shown below, the laser must be serviced at an
authorized service center.
