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

RelativeReagentLevel is defined by IRDI as ABP557#001 which states “relative filling level of auxiliary reagent”.

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

DetectorZeroSignal is defined by IRDI as ABP551#001 which states “reading of the detector before injection of the sample”.

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)”.

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

SampleGasVolumeFlow is defined by IRDI as ABP562#001 which states “volume flow of a sample gas through a detection system”.

The components of ITocSignalConditionSetType have additional references which are defined in Table 47.
