3.3.2. ANALOG OUTPUT Connections
The analog outputs for the M300EU are different from those of the M300E/EM. Unlike the M300E/EM which can include options for measuring both O2 and CO, the M300EU is a single gas analyzer (CO) and therefore does not require the fully configurable version of the analog outputs. The following information replaces that found in Section 3.1.2.2 of the M300E/EM Operators Manual (P/N 04288).
The M300EU is equipped with several analog output channels accessible through a connector on the back panel of the instrument.
•Channels A1 and A2 output a signal that is proportional to the CO concentration of the sample gas.
•The default analog output voltage setting of these channels is 0 to 5 VDC with a reporting range of 0 to 500 ppb.
•An optional Current Loop output is available for each.
•The output labeled A4 is special. It can be set by the user to output any one a variety of diagnostic test functions.
•The default analog output voltage setting of these channels is also 0 to 5 VDC.
•See Section 6.2.2 for a list of available functions.
•There is NO optional Current Loop output is available for Channel A4.
The following table lists the default settings for each of these channels.
