The Analog In connector is used for connecting external voltage signals from
other instrumentation (such as meteorological instruments) and for logging these
signals in the analyzer's internal DAS. The input voltage range for each analog
input is 0-10 VDC, and the input impedance is nominally 20kΩ in parallel with
0.1µF.

Pin assignments for the Analog In connector are presented in Table 3-4.

See Section 7 for details on setting up the DAS.
The T802 is equipped with several analog output channels accessible through the
ANALOG OUT connector on the rear panel of the instrument. The standard
configuration for these outputs is VDC. An optional current loop output is
available for each (Section 3.3.1.4).
When the instrument is in its default configuration, channels A1 and A2 output a
signal that is proportional to the O
be used for connecting the analog output signal to a chart recorder or for
interfacing with a data logger.
If the optional CO sensor is installed, A3 outputs a signal proportional to the

CO concentration of the sample gas.
