Current-Input Fuses

The 400 mA and 10 A inputs are protected by user-replaceable fuses.
•
The 400 mA input is protected by a fuse (F2) rated at 440 mA, 1000 V (fast blow),
10,000 A minimum breaking capacity (Fluke Part No. 943121).
•
The 10 A input is protected by a fuse (F1) rated at 11 A, 1000 V (fast blow),
10,000 A minimum breaking capacity (Fluke Part No. 803293).
For protection against fire or arc flash, replace a blown fuse
only with one from Fluke.
To test for a blown Current Input Fuse:
1. With the Meter powered up, plug a test lead into the VΩGER connector.
2. Press N.
3. Insert the other end of the test lead into the 400 mA input connector.
If the fuse is good, the Meter will read less than 200 Ω. If the fuse is blown, the
Meter will read overload.
4. Remove the probe from the 400 mA connector and insert into the 10 A
connector.
