Data Acquisition System (DAS) and APICOM Teledyne API – Model T300/T300M CO Analyzer

•
CALDAT: Logs new slope and offset of CO measurements every time a zero or
span calibration is performed and the result changes the value of the slope
(triggering event:
SLPCHG ). The CO stability data to evaluate if the calibration
value was stable are also stored.
•
This data channel will store data from the last 200 calibrations and can be used
to document analyzer calibration and is useful in the detection of the in slope
and offset (instrument response) when performing predictive diagnostics as part
of a regular maintenance schedule.
•
The CALDAT channel collects data based on events (e.g. a calibration
operation) rather than a timed interval and therefore does not represent any
specific length of time. As with all data channels, a date and time stamp is
recorded for every logged data point.
These default Data Channels can be used as they are, or they can be customized from the
front panel to fit a specific application. They can also be deleted to make room for
custom user-programmed Data Channels.
Appendix A-5 lists the firmware-specific DAS configuration in plain-text format. This
text file can either be loaded into APICOM and then modified and uploaded to the
instrument or can be copied and pasted into a terminal program to be sent to the
analyzer.

Sending a DAS configuration to the analyzer through its COM ports will
replace the existing configuration and will delete all stored data. Back up
any existing data and the DAS configuration before uploading new
settings.
