Rear-Input Current Fuse F2 (Rear Inputs Option)
The rear input option includes a fuse (F2) to limit the current at the rear-input A terminal
to 2A. The fuse is located at the rear of the Multimeter just to the left of the current input
terminal (A). A half-twist of the fuse cap releases the fuse for inspection or replacement.
Use the fuse specified in Table 4-2 when replacement is necessary.

Self Test
This section of the manual contains a collection of the error codes which might be
generated either on the display of the Multimeter or by way of the IEEE-488 system bus.
Error codes described in this section are shown in tabular form with both the error codes
and the descriptions of the most likely faults, causes, or conditions. Typically, the error
codes contain two parts, a four digit address code and a two digit id code. However, some
error codes consist only of the four digit address. The combination for any given code is
identified by the presence or absence of the id column in the error code table.
The error codes are classified as Self-Test Errors, Fatal Errors, Execution Errors, and
Device Dependant Errors. All error conditions other than Fatal Errors are recoverable.
For help in determining what to do in the event of a self-test error, make a note of the full
error message and contact your nearest Fluke Service Center.
Self-Test Errors
When a Self-Test is run and successfully completed no error messages result and the
Multimeter is considered operational. If a self-test error does occur, an error message
beginning with
self test failed
shows on the display. A function indicator and a
test id number follow to complete the message. See Table 4-3 for descriptions of the self-
test errors that might occur.
