6.7 Bulb Replacement (Fiber-optic Lighting)
NOTE:
The lights of a fiber-optic metrology system generate heat
. To preserve lamp
life and reduce unnecessary heat buildup, turn the lights down when the
system is
not in use.

supply before opening the electronics enclosure.
CAUTION:
The lamp bulbs are very hot and can cause burns if not allowed to
cool
properly.
Do not touch any part of the new bulb when inserting
.
The inner reflective sur
face
of the lens and the filament housing are particularly susceptible to dam
age.
Oils
from fingers and hands can contaminate the surface and shorten the
bulb life.
Use
a clean cloth or tissue, or wear clean latex gloves to handle the
new bulb.
Do not to get any part of a tissue or cloth caught in the bulb contacts to avoid a
potential fire hazard.
The bulb must be fully seated in the socket to prevent arcing and premature
failure
of the bulb and damage to the socket.
