CONNECTING ANALOG INPUTS (OPTION)
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.
Figure 3-8: Analog In Connector
Pin assignments for the Analog In connector are presented in Table 3-4.

CONNECTING ANALOG OUTPUTS
The T300 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.
