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 a smooth, flat, stable surface
that is level in both directions and turn on both
vertical beams (Figure
G
#1).
2.
Mark two short lines where the beams cross
(
a
,
b
) and also on the ceiling
c
,
d
. Always
mark the center of the beams’ thickness (Figure
G
#2).
3.
Pick up and rotate the laser 180 º, and position it
so the beams line up with the marked lines on the
level surface (
e
,
f
) (Figure
G
#3).
4.
Mark two short lines where the beams cross on
the ceiling
g
,
h
.
5.
Measure the distance between each set of
marked lines on the ceiling (
c
,
g
and
d
,
h
). If the measurement is greater than the
values shown below, the laser must be serviced at
an authorized service center.
Ceiling Height
Allowable Distance
Between Marked Lines
2.5 m (8’) 1.5 mm (1/16”)
3 m (10’) 2.0 mm (3/32”)
4 m (14’) 2.5 mm (1/8”)
6 m (20’) 4 mm (5/32”)
9 m (30’) 6 mm (1/4”)
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.
Place the laser on a smooth, flat, stable surface
that is level in both directions, as shown in Figure
H
#1.
2. Turn the laser ON.
3. Turn on both vertical beams.
4. Along the front laser beam, mark three locations
a
,
b
, and
c
; where
b
is at the midpoint of the
laser beam.
5.
Position the laser so the down dot is over
b
and
the front laser beam is aligned with
c
(Figure
H
#2).
6. Mark a location
e
along the side laser beam at
least 3m (10’) away from the laser.
7.
Turn the laser clockwise 90º.
8.
Position the laser so the down dot is over
b
and
the front laser beam is aligned with
e
(Figure
H
#3).
9.
Along the side laser beam, mark
f
near
a
.
10.
Measure the distance between
a
and
f
.
11.
If your measurement is greater than the
Allowable Distance Between
a
&
f
for the
corresponding Distance from
b
to
a
in the
following table, the laser must be serviced at an
authorized service center.
