11.5.8.3. Status Outputs

The procedure below can be used to test the Status outputs.
• Connect a cable jumper between the "-" pin and the "!" pin on the status output
connector.
• Connect a 1000 Ω resistor between the +5 V and the pin for the status output that
is being tested.
• Connect a voltmeter between the "-" pin and the pin of the output being tested
(Table 11-7).
• Under the DIAG / SIGNAL I/O menu (Section 6.7.2), 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.

11.5.8.4. Control Inputs

The control input bits can be tested by the following procedure:
• Connect a jumper from the +5 V pin on the STATUS connector to the +5 V on the
CONTROL IN connector.
• Connect a second jumper from the '-' pin on the STATUS connector to the A pin on
the CONTROL IN connector. The instrument should switch from SAMPLE mode to
ZERO CAL R mode.
• Connect a second jumper from the '-' pin on the STATUS connector to the B pin on
the CONTROL IN connector. The instrument should switch from SAMPLE mode to
SPAN CAL R mode.
In each case, the M100E should return to SAMPLE mode when the jumper is removed.
