Data Acquisition System (DAS) & APICOM Teledyne API T801 NDIR CO2 Analyzer Operation Manual
132
DETAILED: Samples seven different parameters related to the operating status
of the analyzer’s. For each parameter:
A value is logged once every minute;
An average of the last 60 readings is calculated once every minute.
The last 480 averages are stored (20 days).
This channel is useful for diagnosing problems that cause the instruments
measurements to drift slowly over time
FAST: Almost identical to DETAILED except that for each parameter:
Samples are taken once per minute and reported once per minute, in effect
causing the instrument to record an instantaneous reading of each parameter
every minute.
The last 360 readings for each parameter are recorded/reported.
This channel is useful for diagnosing transients; spikes and noise problems.
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 either can 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.
IMPORTANT
IMPACT ON READINGS OR DATA
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.
