#112 Beam Power Adjustment
Tools required: laser power meter Time:
small straight slot screwdriver .25
1. Position power meter over beam output aperture.
Caution: If P.C.B has been replaced, start the adjustment procedure by turning
the potentiometer 5 to 6 turns counter clock wise to reduce the power.
2. Rotate beam power adjustment potentiometer to obtain an output power
at the aperture of about 1mw. This may vary depending on the optics.
Final power should be checked with all optics in place (.45mw to .55mw).
#113 Vertical Vial Calibration Procedure
Tools required: Infra-Red viewer (part1) Time:
Optical level (part 1) .25
Plumb line (part 2)
DANGER: During this procedure, laser emissions
from the beam aperture will be class IIIB! Take all
necessary precautions to avoid exposure.
1. Procedure using Infra-Red Viewer:
a. Remove laser housing (see procedure #101).
b. Attach the laser to the vertical adapter accessory (model V1).
c. Be sure the beam projects away from
any contact with people. You
will need approximately 50 feet (15 meters) of range to project to your far
point. Apply power to the laser and, using the infra-red viewer, adjust the
laser (using the S axis leveling foot) until the beam is approximately
horizontal.
d. Dis-connect power from the laser and set-up an optical level (or
another laser) as a level reference and adjust the instrument height to the
center of the output aperture of the laser to be calibrated.
DANGER:
Do not sight or look directly into the laser
beam with the optical instrument! Avoid
all exposure to the beam.
e. Transfer the elevation of the output aperture to the far point. Make a
mark at this height on the far point.
f. Re-connect power to the laser so that the beam is on again.
