Data Acquisition System (DAS & APICOM 

Teledyne API T803 CO2/O2 Analyzer Operation Manual 

 

CALDAT: Data channels log new slopes and offsets of measurements each time 
an O

2

 zero or span calibration is performed and the result changes the value of the 

slope (triggering event: SLPCHG).  Although there is a separate data channel for 
CO

2

 (CALCO2), this channel could be configured to include both O

2

 and CO

2

. 

  This data channel will store data from the last 200 calibrations and can 

be used to document analyzer calibration; it also is useful for detecting 
trends 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. 

CALCO2: Same as for CALDAT above, but this channel is configured to log 
data for CO

2

. 

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.
