Teledyne API Model 300M CO Analyzer Instruction Manual, 04033, Rev. A

4.11 Data Acquisition System (DAS)

The Model 300M contains a flexible and powerful built in data acquisition system (DAS) that enables the analyzer to store concentration data as well as many 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 Model 300M software. These are described Section 4.11.1. For more information on programming custom Data Channels, a supplementary document containing this information can be requested from Teledyne API.

4.11.1 Data Channels

The function of the Data Channels is to store, report, and view data from the analyzer. The data may consist of Carbon Monoxide concentration, or may be diagnostic data, such as the sample flow or detector output.

The M300M comes pre-programmed with a set of useful Data Channels for logging Carbon Monoxide 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-VIEWmenu. 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.
