and long-term reliability. An LED indicator is
also provided to confirm when data associ-
ated with the master/slave mode data link is
present.
The Model 93 provides two automatic test
sequences: auto test and continuous auto
test. The auto test sequence is the unit’s
fastest test method, specifically included to
support busy field broadcast applications.
It takes less than six seconds from the time
the auto test pushbutton is pressed until
the test results are displayed. In the chan-
nel mode, auto testing begins with channel
1 and continues on through to channel 12.
When selected for pin mode auto testing will
begin with pin q and continue on through
pin g. (While available for manual testing
as a group, pins r, m, and k are not part of
the auto test sequences.) During the auto
test sequence the LED display will indicate
which channel or pin is being tested.
At the end of the entire test sequence one
of three result messages will then display:
ALL OK, FAIL, or OPEN. As expected, when
the result is ALL OK the W1 is ready for use.
A FAIL message will display if one or more
errors are detected. And OPEN will display
should no pins be detected as being con-
nected. This typically indicates that the
cable designated for testing has not been
correctly connected to the Model 93.
The continuous auto test sequence is
enabled whenever the auto test button is
pressed and held. Using this test sequence,
the Model 93 will test all channels or pins
followed by a summary results message.
However, the difference with this test se-
quence is that the results for each individual
channel or pin will be displayed as testing
progresses. Whenever a defective channel
or pin is detected the sequence will pause
momentarily while the right two digits dis-
play the applicable error information. The
Press and hold auto
test button to enable
continuous auto test.
