Current-Input Fuses - Fluke 8808A User Manual

Current-Input Fuses

The 200 mA and 10 A inputs are protected by user-replaceable fuses.
•
The 200 mA input is protected by a fuse (F2) rated at 440 mA, 1000 V (fast
blow), 10,000 A minimum breaking capacity.
•
The 10 A input is protected by a fuse (F1) rated at 11 A, 1000 V (fast blow),
10,000 A minimum breaking capacity.
For protection against fire or arc flash, replace a blown fuse
with a fuse of an identical rating.
To test the current-input fuses:
1. Turn on the Meter and plug a test lead into the INPUT VZYR HI terminal.
2. Press O.
3. Press V to set the range to 200 Ω. Only the 200 Ω, 2 kΩ, and 20 kΩ ranges
can be used to test the mA input fuse.
4. Insert the other end of the test lead into the mA terminal. If the fuse is good, the
Meter displays a reading of <10 Ω. If the fuse is blown, the Meter displays 0L to
indicate an overload.
5. Remove the test lead from the mA terminal and insert it into the 10 A terminal.
If the fuse is good, the Meter displays a reading of <2 Ω. If the fuse is blown, the
Meter displays 0L to indicate an overload.
To avoid electric shock, remove the power cord and any test
leads from the Meter before opening the current-input fuse
cover.
