1.
At the long end of the room, place the tool one foot from side wall "A" and
8 feet from the facing wall. Slide the Pendulum Switch
Allow a few seconds for the pendulum to stabilize.
2.
Cut four pieces of painters tape or masking tape, each piece at least two inches long.
Adhere the tape strips on the walls over the laser beam at locations A, B, C and D.
3.
Using a ruler, scribe a line at the center of the laser beam on each piece of tape.
Scribe lines underneath the laser beam on the remaining pieces of tape.
4.
Push the compensator lock button to the LOCK position. Relocate the tool
across the room and position it one foot from the wall at position "D" at the same
distance from the front wall as in the previous step. Slide the Pendulum Switch
the UNLOCK position and wait until the beam stabilizes. Adjust the height of
the tool until the laser beam is centered on the prescribed line at position "D".
5.
Inspect the laser beam impression on every piece of tape. Scribe a line at
the beam's center and the beam's underside on all every piece of tape. If the
distance variation between the two lines is less than the specified accuracy
(1/8 in (3.2 mm) at 33 ft (10 m)), the tool is within the required calibration
specifications and is ready for use. NOTE: 1/8 in @ 33 ft = 0.004 in @ 1 ft
(3.18 mm @ 10.06 m) the level laser beam is calibrated.
