Level Calibration Check (Y-axis)
1.
Set up a tripod between two walls that are at least 50 feet apart. The
exact location of the tripod is not critical.
2.
Make sure that the top of the tripod is roughly level.
• The laser will self-level only if the top of the tripod is within ±
5˚ of level.
• If the laser is set up too far out of level, it will beep when it
reaches the limit of its leveling range. No damage will be done
to the laser, but it will not operate in an “out of level” condition.
3.
Attach a tripod adapter (Figure
G
1
) to the laser unit. The
adapter may be assembled to the bottom for level mode (Figure
G
2
) or to the side for plumb (vertical) mode (Figure
I
3
).
4.
Place the laser with the attached adapter on the tripod and
screw the threaded knob on the tripod into the female thread on
the tripod adapter.
5.
Position the laser unit on the tripod so that the laser’s Y-axis
points directly toward one of the walls (Figure
N
1
).
6.
Turn the laser unit on and allow it to self-level.
7.
Where the beam appears on the left wall, mark point A, and where
the beam appears on the right wall mark point B.
8.
Turn the laser unit 180º so that the Y-axis points directly toward
the opposite wall (Figure
N
2
).
9.
Allow the laser unit to self-level.
10.
Where the beam appears on the left wall, mark point AA, and
where the beam appears on the right wall mark point BB.
11.
Calculate the Total Error using the following equation:
Total Error = (AA-A) - (BB-B)
12.
If your Total Error measurement is greater than the Allowable
Error for the corresponding Distance Between Walls in the
following table, the laser must be serviced at an authorized
service center.
L (Distance Between Walls) Allowable Error
40′ (15m) 3/64” (1.5mm)
50′ (20m) 1/16” (2mm)
70′ (25m) 3/32” (2.5mm)
100′ (30m) 1/8” (3mm)
Plumb Error Check
Perform this check using a wall that is no shorter than the tallest wall
for which this rotary laser will be used (Figure
O
).
1.
Using a standard plumb bob as a reference, mark the top and
bottom of a wall. (Be sure to mark the wall and not the oor or
ceiling).
2.
Position the rotary laser securely on the oor approximately 3”
(1m) from the wall.
3.
Turn the laser on and point the laser dot at the mark on the
bottom of the wall.
4.
Using the or arrow on the Remote Control (Figure
B
6
or
B
7
), rotate the dot upwards.
5.
If the center of the dot scans over the mark on the top of the
wall, the laser is properly calibrated.
Using the Laser
Using the Laser on a Tripod
1.
Position a tripod securely and set it to the desired height. Make
sure that the tripod has a 5/8”-11 threaded screw to ensure
secure mounting of the laser unit.
2.
Make sure that the top of the tripod is roughly level.
• The laser will self-level only if the top of the tripod is within ±
5˚ of level.
• If the laser is set up too far out of level, it will beep when it
reaches the limit of its leveling range. No damage will be done
to the laser, but it will not operate in an “out of level” condition.
