Accessing the Fuses
The Calibrator uses fuses to protect both the line-power input and measurement inputs.
The following sections describe the replacement procedures and lists the appropriate
fuses used in the Calibrator.
Line-Power Fuse
The Calibrator has a line-power fuse in series with the power supply. Table 2 indicates
the proper fuse for each line voltage selection. This fuse is located on the rear panel.
To replace this fuse:
1. Unplug the power cord from the Calibrator.
2. Locate the fuse holder on the rear panel of the Calibrator labeled “Power Fuse.”
3. Using a flat-blade screwdriver, unscrew the fuse holder using the slot on the end of
the fuse holder.
4. Replace the fuse with one that is rated for the line voltage selected. See Table 2.
5. Reinsert the fuse holder and screw it into the socket.
XW Warning
To avoid electric shock or fire, do not use makeshift fuses or
short-circuit the fuse holder.

Measurement Input Fuses
The Amps (A) terminal of the METER input, the HI terminal of the OUPUT terminals,
and the L terminal or the RCD terminals are protected by fuses at the rear of the
Calibrator.
To replace these fuses:
1. Unplug the power cord from the Calibrator.
2. Locate the fuse holder for the measurement input on the rear panel of the Calibrator.
3. Using a flat-blade screwdriver, unscrew the fuse holder using the slot on the end of
the fuse holder.
4. Replace the fuse with one that is rated for the selected input. See Table 3.
5. Reinsert the fuse holder and screw it into the socket.
W Caution
To avoid damaging the Calibrator, use only the fuse specified
for each of the measurement inputs.
