Testing the Fuses

Before measuring current, test the appropriate fuse as shown in Figure 9. If the tests give readings other than those shown, have the meter serviced.

WWarning

To avoid electrical shock or personal injury, remove the test leads and any input signals before replacing the battery or fuses. To prevent damage or injury, install ONLY specified replacement fuses with the amperage, voltage, and speed ratings shown in Table 9.
