Principles of Operation Teledyne API - T100 UV Fluorescence SO2 Analyzer
316
When the TPC feature is enabled, the analyzer’s SO
2
concentration divided by a factor
call PRESSCO which is based on the difference between the ambient pressure of the
sample gas normalized to standard atmospheric pressure (Equation 13-6). As ambient
pressure increases, the co
mpensated SO
2
concentration is decreased.

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 API 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 0.
