Adjusting Level Accuracy (Calibration)
Without moving your checking setup, make a mark on the 2 X $ halfway between A1 and A2
(call it C). The laser must be calibrated to bring the beam to the center mark C.
IMPORTANT: Before calibrating, ensure that the instrument housing is level by placing a
small carpenter’s level on top of the unit, parallel with the beam. Do not move the unit: only
adjust the single centerline leg or trivet point until the housing is level.
Do not enter calibration mode or attempt adjustment unless it is planned to change accuracy.
Accuracy adjustment should be performed carefully, by personnel who understand basic
adjustment principles.
If you’ve made changes you do not wish to save, turn the laser off.

When SET appears, the height of the laser beam can be

A and move the beam until it is at C.
Use the
Center Line
button on the remote to move the
beam up; use the
Standby (ZZZ)
button on the Remote
to move the beam down.
