CHECKING ACCURACY – VERTICAL BEAMS (FIG. G)
Checking the vertical (plumb) calibration of the
laser can be most accurately done when there is
a substantial amount of vertical height available, ideally
30' (9m), with one person on the floor positioning
the laser and another person near a ceiling to mark
the position of the 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.
Place the laser on the floor and turn on both
vertical beams.
2.
Mark position (f) where the beams cross on the
floor position, also marking position (g) on the floor
and also marking where the beams cross on the
ceiling (h). Always mark the center of the beams'
thickness.
3.
Rotate the laser 180 degrees, and reposition it so
the beam crossing is exactly on the original marks
(f,g) on the floor.
4.
Mark the position where the beams cross on the
ceiling (j).
5.
Measure the distance between the two ceiling
marks (h, j). If the measurement is greater than the
values shown below, the laser must be serviced at
an authorized service center.

CHECKING 90º ACCURACY BETWEEN VERTICAL
BEAMS (FIG. H)
Checking 90º accuracy requires an open floor area at
least 33' x 18' (10m x 5m). Refer to Figure H for the
position of the laser at each step and for the location
of the marks made at each step. Always mark the
center of the beams' thickness.
1.
Set up the laser in one corner of the floor and turn
on the side vertical beam.
2.
Mark the center of the beam at three locations
(a, b and c) on the floor along the laser line. Mark
b should be at the midpoint of the laser line.
3.
Move the laser to mark b and turn on both vertical
beams.
4.
Position the beam crossing precisely at mark b,
with the forward beam aligned with mark c.
5.
Mark a location (d) along the side vertical beam at
least 18' (5m) away from the unit.
6.
Rotate the laser over mark b so that the side
vertical beam now passes through mark d.
7.
Mark the location (e) where the side vertical beam
passes by mark a.
8.
Measure the distance between marks a and e. If
the measurement is greater than the values shown
below, the laser must be serviced at an authorized
service center.
