6.7.1.2. DAS Parameters

Data parameters are types of data that may be measured and stored by the DAS. For each Teledyne Instruments analyzer model, the list of available data parameters is different, fully defined and not customizable. Appendix A-5 lists firmware specific data parameters for the analyzer. DAS parameters include things like CO2 concentration measurements, temperatures of the various heaters placed around the analyzer, pressures and flows of the pneumatic subsystem and other diagnostic measurements as well as calibration data such as slope and offset.

Most data parameters have associated measurement units, such as mV, ppb, cm³/min, etc., although some parameters have no units. With the exception of concentration readings, none of these units of measure can be changed. To change the units of measure for concentration readings See Section 6.8.6.

Note

DAS does not keep track of the unit of each concentration value and DAS data files may contain concentrations in multiple units if the unit was changed during data acquisition.

Each data parameter has user-configurable functions that define how the data are recorded:

EFFECT

Instrument-specific parameter name. INST: Records instantaneous reading.

AVG: Records average reading during reporting interval.

MIN: Records minimum (instantaneous) reading during reporting interval.

MAX: Records maximum (instantaneous) reading during reporting interval.

SDEV: Records the standard deviation of the data points recorded during the reporting interval. Decimal precision of parameter value (0-4).

OFF: stores only the average (default).

ON: 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 GFC 7000TA provides about 30 parameters). However, the number of parameters and channels is ultimately limited by available memory.
