3.3.1.3. CONNECTING ANALOG OUTPUTS
The GFC7001T 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 CO concentration of the sample gas. Either can be used for
connecting the analog output signal to a chart recorder or for interfacing with a
datalogger.
Output A3 is only used on the GFC7001T/GFC7001TM if the optional CO
2
or O
2
sensor
is installed.
Channel A4 is special. It can be set by the user (see Section 5.9.8.1) to output any one
of the parameters accessible through the <TST TST> buttons 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.
