Model 360E Instruction Manual Getting Started
3.1.2.2. Output Connections
The M360E 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 on the Model 306E 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.

The default analog output voltage setting of the 360E CO2 Analyzer is 0 – 5 VDC with a range of 0 –
500 ppm.
TO change these settings, see Sections 6.13.4 and 6.8 respectively.
