How to Replace the Current Fuses
The current fuses are accessible for the bottom of the Calibrator. These fuses protect the
3A and 20A outputs from over-current. Table 7-2 lists the fuse part numbers for the two
current fuses. To replace a current fuse:
1.
Turn the Calibrator over on its top.
2. Remove the two screws with a Phillips head screwdriver as shown in Figure 7-2.
