Model GFC7000TA Carbon Dioxide Analyzer

6.7. SETUP DAS: Using the Data Acquisition System (DAS)

The GFC 7000TA analyzer contains a flexible and powerful, internal data acquisition system (DAS) that enables the analyzer to store concentration and calibration data as well as a host of diagnostic parameters. The DAS of the GFC 7000TA can store up to about one million data points, which can, depending on individual configurations, cover days, weeks or months of valuable measurements. The data are stored in non-volatile memory and are retained even when the instrument is powered off. Data are stored in plain text format for easy retrieval and use in common data analysis programs (such as spreadsheet-type programs).

The DAS is designed to be flexible, users have full control over the type, length and reporting time of the data. The DAS permits users to access stored data through the instrument’s front panel or its communication ports. Using APICOM, data can even be retrieved automatically to a remote computer for further processing.

The principal use of the DAS is logging data for trend analysis and predictive diagnostics, which can assist in identifying possible problems before they affect the functionality of the analyzer. The secondary use is for data analysis, documentation and archival in electronic format.

To support the DAS functionality, Teledyne Instruments offers APICOM, a program that provides a visual interface for remote or local setup, configuration and data retrieval of the DAS (Section 6.7). The APICOM manual, which is included with the program, contains a more detailed description of the DAS structure and configuration.

The GFC 7000TA is configured with a basic DAS configuration, which is enabled by default. New data channels are also enabled by default but each channel may be turned off for later or occasional use. Note that DAS operation is suspended while its configuration is edited through the front panel. To prevent such data loss, it is recommended to use the APICOM graphical user interface for DAS changes.

The green SAMPLE LED on the instrument front panel, which indicates the analyzer status, also indicates certain aspects of the DAS status:

LED STATE

DAS Status

OFF

System is in calibration mode. Data logging can be enabled or disabled for this mode.

 

Calibration data are typically stored at the end of calibration periods, concentration data are

 

typically not sampled, diagnostic data should be collected.

BLINKING

Instrument is in hold-off mode, a short period after the system exits calibrations. IDAS

 

channels can be enabled or disabled for this period. Concentration data are typically disabled

 

whereas diagnostic should be collected.

ON

Sampling normally.

The DAS can be disabled only by disabling or deleting its individual data channels.
