).
C 5
Checking the horizontal scan calibration of the
laser requires two walls at least 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.
Make sure the laser is facing straight ahead.
).
2. Turn on the laser's horizontal beam 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' (9 m). Mark the center of
the beam (a).
3. Pivot the laser approximately 90˚ to bring the
three
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.
• If the measurement is greater than the values
shown below, the laser must be serviced at an
authorized service center.

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
