.
To adjust the Z-axis:
1.
Remove the branch unit cover.
2.
Refer to Figure 8-4. Remove the branch
unit cover plate. If the HV is ON at this
time, it will automatically shut OFF. If
there is any abnormality, the laser will
need to be reset.
3.
Refer to Figure 8-5. Remove the fiber-
scope holder from the storage position and
mount it to the branch mirror position in
the branch base. Mount the fiberscope in
the holder.
4.
Attach the fiber optic cable to the
input focusing unit, as described in
Chapter 5 under
Optical Fiber
Connection.
5.
Remove the rubber cap from the output
end of the fiber optic cable. Stabilize
the fiber in a position where the light
from a fluorescent lamp or other light
source enters the fiber.
CAUTION:
Be careful to avoid
dust or dirt contamination of the
fiber end face, and do not exceed
the minimum bend radius of the
fiber during this procedure (refer
to Table 8-1).
