Model GFC7000TA Carbon Dioxide Analyzer

9.5.4. Temperature and Pressure Compensation

Changes in pressure can have a noticeable, effect on the CO2 concentration calculation. To account for this, the Model GFC 7000TA software includes a feature which allows the instrument to compensation of the CO2 calculations based on changes in ambient pressure.

The TPC feature multiplies the analyzer’s CO2 concentration by a factor which is based on the difference between the ambient pressure of the sample gas normalized to standard atmospheric pressure. As ambient pressure increases, the compensated CO2 concentration is increased.

9.5.5. Internal Data Acquisition System (DAS)

The DAS is designed to implement predictive diagnostics that stores trending data for users to anticipate when an instrument will require service. Large amounts of data can be stored in non-volatile memory and retrieved in plain text format for further processing with common data analysis programs. The DAS has a consistent user interface in all Teledyne Instruments analyzers. New data parameters and triggering events can be added to the instrument as needed.

Depending on the sampling frequency and the number of data parameters the DAS can store several months of data, which are retained even when the instrument is powered off or a new firmware is installed. The DAS permits users to access the data through the instrument’s front panel or the remote interface. The latter can automatically download stored data for further processing. For information on using the DAS, refer to Sections 6.12.
