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.

1 See Table A-6 of M300E/EM Appendix A for definitions of these iDAS data types 2 Optional current loop outputs are available for analog output channels A1& A2.

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. Pin-outs for the analog output connector are:
