5.5.7 DAS Commands and Message
The M200A contains a flexible and powerful built in data acquisition system (DAS) that enables
the analyzer to store concentration data as well as diagnostic parameters in its battery backed
memory. This information can be printed out through the RS-232 port. The diagnostic data can
be used for performing “Predictive Diagnostics” and trending to determine when maintenance
and servicing will be required.
To print out the properties of all of the data channels enter:
D PRINT
To print the properties of just a single data channel enter:
D PRINT "name”
For example to print the properties of the CONC data channel enter:
