Fluke 6060B - Section 4 D Troubleshooting and Repair

Section
4D
Troubleshooting
and
Repair
4D-1.
INTRODUCTION
Usually,
the
Generator is
most
easily repaired by
identifying
the
defective
module
and
replacing
it
through
the Module
Exchange Program.
Alternately,
you
may
wish
to
troubleshoot
down to the
component
level
and replace the
defective part.
This
section of
the
manual
provides
the
necessary
information for
both repair
methods.
After
any
module
repair
or
replacement, the
Performance Tests
should be done
to
verify
the
performance
of the
Generator.
Signal
Generator
problems are
generally
caused
by
operator
error,
out-of-spec
performance, or by
catastrophic
failure.
The
correction
strategy
is
different
in each
case.
Although
most
operator errors
are detected and
indicated, some are
not, and
therefore,
may
be
mistaken
for an
out-of-spec
condition.
Those
operator errors
that are
detected
are
indicated
with
either
a steady
or
flashing ‘UNCAL’
indicator.
Consult
the
Generator
Specifications
in
Table
1-1
and
Section 2 in this
manual
for more
inforniation
on
Generator
operation.
Out-of-spec
performance
is
usually corrected by
performing the
appropriate
adjustment
procedure(s).
Use
the
Performance
Tests to
determine
which
parameters need
adjustment.
Refer
to adjustment
paragraphs in this
section
for more
information.
If the
problem is
not an
operator
error and is not
corrected by
adjustment,
the
Generator
has a
catastrophic
failure.
Then the
task
is to isolate the
fault
and make
appropriate
repairs.
The
UNCAL
and
self-test
failure codes usually
provide a good
indication of
the
cause of
the problem.
Using the
Performance Tests in
this
situation may
help to
determine
which
parameters
are not affected.
4D-2.
MODULE
REPLACEMENT
This
repair method
involves
identifying and replacing
the problem
module.
The
replacement
module
may be obtained
using the Module
Exchange Program
or
from your
spare
module
stock,
which may
then be
restored using the
Module
Exchange
Program.
Use
the
information in
the
Troubleshooting
section to
diagnose
the problem. To
help you
identify
the problem
module, you
may
call your local
Fluke
Technical
Center for
troubleshooting
assistance. Once
the Fluke service
technician believes
the problem
module is
identified, a
replacement
module
can be shipped
prepaid by an
overnight air
carrier.
After
the operator
verifies that
the
replacement module
corrects the
problem,
return
the
defective
module
using the
shipping
container and
including
the prepaid
return shipping
papers and
label.
