5.3.3. Data Acquisition System (DAS)
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 viewed from the front panel or 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.
The logged parameters are stored in what are called “Data Channels.” Each Data Channel can
store multiple data parameters. The Data Channels can be programmed and customized from the
front panel. A set of default Data Channels has been included in the M200A software. For more
information on programming custom Data Channels, a supplementary document containing this
information can be requested from Teledyne API.

concentration, or may be diagnostic data, such as the sample
flow or reaction cell pressure.
The M200AH comes pre-programmed with a set of useful Data Channels for logging
concentration and predictive diagnostic data. The default Data Channels can be used as they are,
or they can be changed by the user to fit a specific application. They can also be deleted to make
room for custom user-programmed Data Channels.
The data in the default Data Channels can be viewed through the SETUP-DAS-VIEW menu.
Use the PREV and NEXT buttons to scroll through the Data Channels and press VIEW to view
the data. The last record in the Data Channel is shown. Pressing PREV and NEXT will scroll
through the records one at a time. Pressing NX10 and PV10 will move forward or backward 10
records. For Data Channels that log more than one parameter, such as PNUMTC, buttons labeled
<PRM and PRM> will appear. These buttons are used to scroll through the parameters located
in each record.
