INTRODUCTION
3-1.
This section provides maintenance procedures and troubleshooting informa-
tion for the Pod and includes repair precautions and disassembly procedures.
Some of these procedures
do not require access to the instrument
and can
be performed
by
the operator. Troubleshooting procedures, which require
the use of the 9132A Service Test
Kit, may require reference to the disas-
sembly instructions found in this section.
The built-in Pod self test (described
in
Section
2
of
the appropriate
microprocessor-specific users manual) detects most Pod malfunctions.
(Table 3-1 in this section contains a list that explains the various self test
failure codes.) Whenever
the
Mainframe displays a message indicating
a
self test error, or whenever the Pod appears to
be
defective or inoperative,
you should make a note
of the message or symptoms. If the Pod
is still
covered under the Warranty, or if you want
to
have the Pod repaired
by
Fluke,
send
the Pod to a Fluke Technical Service Center for repair
as
described below. If you plan
to
troubleshoot and repair the Pod yourself,
continue
to “Troubleshooting Procedures” further on in
this section.
CAUTION
The Pod and module
PCAs (Printed Circuit
As-
semblies)
use
numerous
surface-mounted
parts.
Replacement of
these
parts requires a re-
flow
soldering technology. Attempting to re-
place
surface-mounted
components using a
soldering iron or other conventional means will
damage the PCA.
