5. Repeat step 4 twice, resulting in a total of 4 marks on the ceiling.
6. The four points should form a circle. Measure its diameter. If this
diameter is less than 1/16" at 25’, the laser is in calibration. If the
plumb beam is out of calibration, and the rotary beam is within
calibration, the laser must be serviced by an authorized Johnson
dealer. No further user adjustments are possible. If both rotary
and plumb beams are out of calibration, follow the steps above
for Accuracy Calibration. It’s possible that damage to the laser
head has caused alignment issues beyond what can be field
repaired, for example if the laser is dropped. In this case, return
the laser to your Johnson dealer for service, as specialty equip-
ment is needed to recalibrate the laser.
