3.5.3. Connecting Analog Outputs

The GFC 7000TA is equipped with several analog output channels accessible through a connector on the back panel of the instrument. The standard configuration for these outputs is mVDC. An optional current loop output is available for each.

When the instrument is in its default configuration, channels A1 and A2 output a signal that is proportional to the CO2 concentration of the sample gas. Either can be used for connecting the analog output signal to a chart recorder or for interfacing with a data logger.

Output A3 is only used if the optional O2 sensor is installed.

Channel A4 is special. It can be set by the user (see Section 6.13.9) to output any one of the parameters accessible through the <TST TST> keys of the units sample display.

To access these signals attach a strip chart recorder and/or data-logger to the appropriate analog output connections on the rear panel of the analyzer.
