SAMPLE-PRESSURE: The ambient pressure of the sample gas as measured by the
instrument’s sample pressure sensor in “Hg-A.

SAMP_PRESS_SLOPE: Sample pressure slope correction factor. The default setting
for Section 6.8 describes the method for enabling/disabling the TPC feature.

13.7.4. 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 Analytical Instruments instruments. 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 Section
6.6.
