ChopperFrequencyDeviation is defined by IRDI as ABP553#001 which states “relative change in the chopper frequency of a detector during a measurement”.

AbsoluteSampleGasPressure is defined by IRDI as ABP560#001 which states “absolute pressure of sample gas inside a detection system”.

SampleCellTemperature is defined by IRDI as ABP556#001 which states “measured temperature of the sample cell”.

SourceResidualLife is defined by IRDI as ABP552#001 which states “degradation of a radiation source expressed as a value between 1 (good) and 0 (bad)”.

The components of INonDispersiveInfraredSignalConditionSetType have additional references which are defined in Table 59.
