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 dis-
played 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 93 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 numeric code for the pin or pins that
are connected. A one-to-one relationship
between the pin being tested and the con-
nected pin is the desired result. If no pin
is detected as being connected to the pin
selected for testing two dashes (- -) will dis-
play. At the end of each full test sequence a
summary result will display: 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 para-
graph. 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 W1
to W1 mode is active will flash. The test
results displayed will be the pin or pins
that are connected to the pin selected for
testing. If no pin is detected as being con-
nected two dashes (- -) will display. Repeat
testing of the selected channel or pin will
take place every two seconds. The dis-
played results will refresh with each test
cycle.
System Mode:
Local Cable Mode: W1-M to XLR-F
When the cable mode is selected for
W1-M to XLR-F the Model 93 is configured
to test W1 “fanouts” that have an W1 male
on one end and twelve 3-pin female XLR
connectors on the other.
Begin testing by connecting the fanout’s W1
male connector to the female W1 connector
located on the right side of the Model 93.
Ensure that a solid connection is made by
“locking” the connectors together using the
outer ring. Each fanout channel can now
be individually tested. Start by plugging the
fanout’s female XLR connector associated
with channel 1 into the male XLR connector
located on the left side of the Model 93. Use
the buttons adjacent to the up and down ar-
rows to select channel 1 for testing. The left
two display digits will indicate the selected
channel. The right two display digits will
indicate the test result. The result will either
display an OK or one or more of the nine
error codes. OK indicates that the connec-
tions associated with channel 1 are correct.
If the E1 error code is displayed, be certain
to use the channel select buttons to manu-
ally “step through” all channels looking
for an OK result. This will identify whether
the fanout’s XLR connector has been la-
beled with the incorrect channel number.
After channel 1 has been tested remove
its associated female XLR connector from
