8. Self-Check and Calibration
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
The instrument must be self-checked before operation. If the
accuracy is found beyond tolerance, user can make some
adjustment according to directions as follows.
X-Direction Accuracy Self-Check
1. For clarity, we define the direction of handle as Y-direction,
and another direction as X-direction
2. Place the unit on a platform or tripod that is 50’ away from a
wall indoors, with the handle facing the wall head-on. Turn the
unit on.
3. Using the detector mark on the wall where the beam hits the wall
and mark that as A.
4. Turn the instrument by 180 degrees, mark the beam as point B.
5. Measure the vertical distance between point A and point B. If A &
B are more than 1/32” apart at 50’, the unit is out of calibration.
6. As shown, turn the instrument by 90° and place it on the
platform, with the operating panel facing you. Perform
12 ©2007 Johnson Level & Tool
50’

X-direction self-check with the same method as Y-direction
self-check, and mark point C and point D by turns.
7. If point C and point D are within 1/32” at 50’, the accuracy is
within tolerance. Otherwise reference section 12 of this
document.
Enter self-calibration
In power off status, press the power and the tilt buttons of the laser unit
simultaneously. Then let go of the power button while still pressing
the tilt button. 10 seconds later, the self-calibration indicator lights
of X direction and Y direction flash 3 times simultaneously. Let go of
the tilt button, the instrument enters self-calibration mode. Remote
control is necessary for self-calibration.
X Direction Self-calibration
Select self-calibration direction
Make X direction of the instrument face to the reference line. Press
X/Y button on the remote control once to select X direction for
self-calibration. The X direction indicator light in the “CALIBRATOR”
area of the instrument keypad is lighted as shown in the following
figure, and the rotator head begins to rotate.

Confirm calibration value
Press ‘ENT’ button on the remote control to
confirm self-calibration value. The Y
direction self-calibration indicator light
will extinguish after pressing this button.
Note: In order to make the calibration effective, you must power off the
instrument after the calibration, and then power it on again. Y-axis
accuracy check is a necessity after X-axis calibration, and X-axis
accuracy check is also a necessity after Y-axis calibration.
Instrument self-calibration will not be fulfilled until both X-axis and
Y-axis accuracy meet the requirement.
