Internal Data Acquisition System (Idas) - Teledyne 100E Instruction Manual

Theory Of Operation Model 100E Instruction Manual
When the TPC feature is enabled, the analyzer's SO concentration divided by a factor
2
call PRESSCO which is based on the difference between the ambient pressure of the
sample gas normalized to standard atmospheric pressure (Equation 10-5). As ambient
pressure increases, the compensated SO concentration is decreased.

Equation 10-5
SAMPLE-PRESSURE: The ambient pressure of the sample gas as measured by the
instrument's sample pressure sensor (see Figure 10-7) in "Hg-A.
SAMP_PRESS_SLOPE: Sample pressure slope correction factor. The default setting for
Section 6.6 describes the method for enabling/disabling the TPC feature.

10.7.4. Internal Data Acquisition System (iDAS)

The iDAS 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 iDAS has a consistent user interface in all T-
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 iDAS can
store several months of data, which are retained even when the instrument is powered
off or a new firmware is installed. The iDAS 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 iDAS, refer to Sections
6.10.
