Operation
It’s now time to actually test cable assem-
blies using the Model 92.
Local Mode Operation
The following four sections provide details
on using the Model 92 when the system
mode is selected for local.
System Mode: Local
Cable Mode: FK37 to FK37
When the cable mode is selected to FK37
to FK37 the Model 92 is ready to test DT12
cable assemblies where both ends are termi-
nated to FK37-type connectors. In this case
the cable-mounted FK37 connectors should
be mated with those on the Model 92. En-
sure that the connectors are “locked” togeth-
er using the threaded rings to ensure that
a reliable interconnection has been made.
Automatic or manual testing can now begin.
Tapping the auto test button will initiate
a rapid scan of all the channels or pins,
depending on whether channel or pin mode
is selected. At the end of the test sequence
one of three messages will display: ALL OK,
FAIL, or OPEN. ALL OK indicates that the ca-
ble assembly is ready to be placed into ser-
vice. FAIL indicates that one or more failures
were detected during the test sequence.
If FAIL displays then manual testing of the
channels or pins should be used to identify
where the specific problem or problems are
located. OPEN indicates that no connections
were detected, most likely the result of one
or both of the FK37 connectors not being
correctly terminated on the Model 92.
Pressing and holding the auto test button for
two seconds will initiate a continuous auto
test mode. The local mode LED will flash
when continuous auto test mode is active.
In this mode each channel or pin will be
sequentially tested and the result displayed
in real time. The left two digits of the display
will indicate the channel or pin being tested
while the right two digits will indicate the
result. In the channel mode the result will
be either OK or one or more of the nine
possible error codes. The label on the front
of the Model 92 contains a brief summary
of the error codes. A detailed description of
the error codes can be found in Appendix A.
In the pin mode the displayed result will be
the pin or pins that are connected. A one-
to-one relationship between the pin being
tested and the connected pin is the desired
result. If no pin is detected as being con-
nected to the pin selected for testing two
dashes (- -) will display. At the end of each
full test sequence a summary result will dis-
play: ALL OK, FAIL, or OPEN. The meaning
of the three possible results is the same as
with the auto test function, discussed in the
previous paragraph. After a slight pause to
display the summary result, the continuous
auto test mode will begin another complete
test of all the channels or pins. To cancel
continuous auto test simply press and
release the auto test, the channel up, or
the channel down select buttons.
At any time manual testing of individual
channels or pins is possible. The buttons
adjacent to the up and down arrows are
used to select the channel or pin to be
tested. The left two digits of the display will
indicate which channel or pin is currently
being tested. The right two digits will display
the results of the test. In the channel mode
the results will be either OK or one or more
of the nine possible error codes.
In the pin mode the light indicating that
FK37 to FK37 mode is active will flash. The
test results displayed will be the pin or pins
that are connected to the pin selected for
