Figure 2-1. Replacing the Line Fuse
Current-Input Fuses
The 100 mA and 10 A inputs are protected by user-replaceable fuses.
•
The 100 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).
W
Warning
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
V
Ω

connector.
2.
Press
N
.
3.
Insert the other end of the test lead into the 100 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

.
4.
Remove the probe from the 100 mA connector and insert into the 10 A
connector.
