How to Replace the Current Fuses
The two Calibrator current outputs are protected by fuses. If the Calibrator is unable to
source current, one or both of the current fuses may be blown.
XW Warning
To avoid electric shock, turn the Calibrator off, remove the
power cord, and wait two minutes to allow the power
assemblies to completely discharge before opening the current
fuse access door.
To replace the current output fuses:
1. Turn off the Calibrator, remove the power cord, and wait two minutes for the power
assemblies to fully discharge.
2. Turn the Calibrator over.
3. Remove the two screws that hold the fuse compartment cover in place and remove
the cover as shown in Figure 7-2.
