8. Self-Check & Fine Calibration
IMP RTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
Horizontal Accuracy (transversely)
1. Locate a wall, set up an elevated tripod 15 feet away from the wall, fix
the laser to the tripod.
2. Rotate the laser until the V1 laser beam faces the wall and power on all
the laser lines, mark the cross dot of V1 and H on the wall as point “A”.
3. Rotate the laser 90º counter-clockwise and mark the cross dot of V2
line and H line as “B”.
4. Measure the distance ‘e’ between “A” and “B”. (See illustration below)
5. If the distance is greater than 3mm (0.125"), then the horizontal line
accuracy is out of tolerance and the laser needs to be calibrated.
When the horizontal line accuracy is out of
tolerance, remove the screw of the
self-calibration port. Use a 3mm hex
wrench to adjust the laser to get a
distance ≤3mm.

Horizontal Accuracy (longitudinal)
1. Set up two grade rods which are 15 feet
away from each other as seen to the right
(or two parallel walls which are more than
15 feet away from each other.)
2. Mount the laser on a tripod 15 feet away
from the left grade rod, level out the bubble
by adjusting the tripod.
3. Power on the laser, mark the cross dot of V1 line and H line on the
grade rod as “C”.
4. Rotate the tripod 180º, mark the cross dot of V2 and H as “D”.
5. Move the tripod 15 feet away from the right grade rod. Line up the
cross dot with point “D” by elevating the tripod.
6. Rotate the laser 180º, measure the distance between the new project-
ed cross dot and point “C”.
7. If the distance is greater than a 3mm (0.125"), the horizontal accuracy
of the laser is out of tolerance and the laser needs to be calibrated.
When the horizontal accuracy is out of
tolerance, remove the screw of the
self-calibration port. Use a 3mm hex
wrench to adjust the weight inside the
laser to make the distance ≤3mm

Note: If you could not calibrate the accuracy through the self-cali-

15. Trouble Shooting
• If the unit does not turn on, check the battery polarity or clean
battery terminals and install new alkaline batteries.
• If the laser does not illuminate, check the battery polarity or clean
battery terminals and install new alkaline batteries.
• If the unit is out of calibration less than 1/4" at 50', follow
calibration procedure in manual.
• If the unit is out of calibration more than 1/4" at 50', contact an
authorized Johnson service center or Johnson Level & Tool's
customer service department.
• If the unit will not calibrate, contact an authorized Johnson service
center or Johnson Level & Tool’s customer service department.
• If the unit beeps and/or flashes constantly, check to see if the unit
is being tilted to angles beyond the self-leveling range. If the unit is
being used for a level application, place onto a surface that is
within the self-leveling range. If it is still beeping and/or flashing,
the unit is out of calibration.
• If the unit turns off after a short time, clean the battery terminals
and install new alkaline batteries. Also, make sure that the on/off
knob is in the on position
