Instrument-specific parameter name. 

: Records instantaneous reading. 

: Records average reading during reporting interval. 

: Records minimum (instantaneous) reading during reporting interval. 

: Records maximum (instantaneous) reading during reporting interval. 

Decimal precision of parameter value (0-4).  

STORE NUM. SAMPLES  OFF: stores only the average (default). 

: stores the average and the number of samples in each average for a parameter. This 

property is only useful when the AVG sample mode is used. Note that the number of 
samples is the same for all parameters in one channel and needs to be specified only for 
one of the parameters in that channel. 

Users can specify up to 50 parameters per data channel (the T100 provides about 30 
parameters). However, the number of parameters and channels is ultimately limited by 
available memory. 

Triggering events define when and how the DAS records a measurement of any given 
data channel. Triggering events are firmware-specific and are listed in Appendix A-5. 
The most common triggering events are: 

  ATIMER: Sampling at regular intervals specified by an automatic timer. Most 

trending information is usually stored at such regular intervals, which can be 
instantaneous or averaged. 

  EXITZR, EXITSP, SLPCHG (exit zero, exit span, slope change): Sampling at the 

end of (irregularly occurring) calibrations or when the response slope changes. 
These triggering events create instantaneous data points, e.g., for the new slope and 
offset (concentration response) values at the end of a calibration. Zero and slope 
values are valuable to monitor response drift and to document when the instrument 
was calibrated. 

  WARNINGS: Some data may be useful when stored if one of several warning 

messages appears. This is helpful for trouble-shooting by monitoring when a 
particular warning occurred. 

A set of default Data Channels has been included in the analyzer’s software for logging 
SO

 concentration and certain predictive diagnostic data.  These default channels include 

but are not limited to: 

CONC: Samples SO

 concentration at one minute intervals and stores an average every 

five minutes with a time and date stamp. Readings during calibration and calibration 
hold off are not included in the data. By default, the last 4032 hourly averages are 
stored. 

PNUMTC: Collects sample flow and sample pressure data at five minute intervals and 
stores an average once a day with a time and date stamp. This data is useful for 
monitoring the condition of the pump and critical flow orifice (sample flow) and the
