Level Calibration Check (Y-axis)
E
Set up a tripod between two walls that are at least 50 feet apart. The
1.
exact location of the tripod is not critical.
Make sure that the top of the tripod is roughly level.
2.
• 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.
Attach a tripod adapter (Figure

adapter may be assembled to the bottom for level mode (Figure
) or to the side for plumb (vertical) mode (Figure

Place the laser with the attached adapter on the tripod and
4.
screw the threaded knob on the tripod into the female thread on
the tripod adapter.
Position the laser unit on the tripod so that the laser's Y-axis

points directly toward one of the walls (Figure
Turn the laser unit on and allow it to self-level.

Where the beam appears on the left wall, mark point A, and where

Turn the laser unit 180º so that the Y-axis points directly toward
8.
the opposite wall (Figure

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.

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 floor or
ceiling).
Position the rotary laser securely on the floor approximately 3"

(1m) from the wall.
Turn the laser on and point the laser dot at the mark on the

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
Position a tripod securely and set it to the desired height. Make
1.
sure that the tripod has a 5/8"-11 threaded screw to ensure
secure mounting of the laser unit.
Make sure that the top of the tripod is roughly level.
2.
• 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.
