8.4 Fuse Replacement
Fuse Replacement is an unusual event, and usually is caused by some electrical fault. The electrical
fault should always be investigated and repaired before fuse replacement. Once the fault is found
and corrected, this procedure should be followed:
Turn off power and unplug the instrument
from AC power. Open the side cover.
Remove the AC power plug from the AC
power block of the instrument.
Use a tool (such as an Allen wrench) to pull
the housing open.
There is a small slot where the tool can be
inserted to pry the door gently open.
