5.3.3 Data Acquisition System (DAS)

The M9110AH 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.
5.3.3.1 Data Channels
The function of the Data Channels is to store, report, and view data from the analyzer. The data
may consist of NO, NO , NO concentration, or may be diagnostic data, such as the sample
x 2
flow or reaction cell pressure.
The M9110AH 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.
