Model GFC7000TA Carbon Dioxide Analyzer

10.5.8.4. Status Outputs

The procedure below can be used to test the Status outputs:

1.Connect a jumper between the “D“ pin and the “” pin on the status output connector.

2.Connect a 1000 ohm resistor between the “+” pin 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 (see table below).

Under the DIAGSIGNAL I/O menu (See Section 10.1.3), 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.

10.5.8.5. Control Inputs – Remote Zero, Span

The control input bits can be tested by the following procedure:

1.Connect a jumper from the +5 pin on the Status connector to the x5V on the Control In connector.

2.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.

3.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.

4.In each case, the GFC 7000TA should return to SAMPLE mode when the jumper is removed.
