To verify that the analog outputs are working properly, connect a voltmeter to the output
in question and perform an analog output step test as described in Section 5.9.2.
For each of the steps, taking into account any offset that may have been programmed
into the channel (refer to Section 5.9.3.4), the output should be within 1% of the nominal
value listed in the Table 11-7 except for the 0% step, which should be within 2-3 mV. If
one or more of the steps is outside of this range, a failure of one or both D/A converters
and their associated circuitry on the motherboard is likely.

Increase the Analog Out (AOUT) Cal Limits in the DIAG>Analog I/O Config menu.
The procedure below can be used to test the Status outputs.
1. Connect a cable jumper between the "-" pin and the "" pin on the status output
connector.
2. Connect a 1000 Ω resistor between the +5 V and the pin for the status output that is
being tested.

3. Connect a voltmeter between the "-" pin and the pin of the output being tested (refer
to Table 11-8).
4. Under the DIAG  SIGNAL I/O menu (refer to Section 5.9.1), scroll through the
inputs and outputs until you get to the output in question. Alternately turn on and off
the output noting the voltage on the voltmeter, it should vary between 0 volts for ON
and 5 volts for OFF.
