CalibrationSetpoint is defined as the input value of a calibration table for a concentration or liquid analysis measurement. Its specific definition depends on the specific type of measurement, e.g. input value of a mass concentration (per volume) table in case of mass concentration (per volume) measurement.

CalibrationActualValue is defined as the digital reading of a value representing a concentration or liquid analysis measurement variable. Its specific definition depends on the specific type of measurement, e.g. digital reading of a value representing a mass concentration (per volume) variable in case of mass concentration (per volume) measurement.

The components of CalibrationPointType have additional references which are defined in Table 164.

3:<DictionaryEntryName> is a placeholder for an object of IrdiDictionaryEntryType that represents a property defined in IEC 61987 Common Data Dictionary (CDD). In instances of CalibrationPointType it shall be replaced by an object of IrdiDictionaryEntryType depending on the type of PAT measurement, following these rules:

For CalibrationSetpoint it shall be replaced by one of the following CDD properties: ABP597#001, ABP600#001, ABP603#001, ABP606#001, ABP609#001, ABP612#001, ABP615#001, ABP618#001 (input values for the calibration of PAT concentration measurement), ABP637#001, ABP621#001, ABP624#001, ABP627#001, ABP630#001, or ABP633#001 (input values for the calibration of PAT liquid analysis measurement). If further types of PAT measurements are defined in the CDD in the future, the corresponding properties of these measurement types will also be permitted.

For CalibrationActualValue it shall be replaced by one of the following CDD properties: ABP598#001, ABP601#001, ABP604#001, ABP607#001, ABP610#001, ABP613#001, ABP616#001, ABP619#001 (digital output values measured during the PAT concentration measurement calibration), ABP638#001, ABP622#001, ABP625#001, ABP628#001, ABP631#001, or ABP634#001 (digital output values measured during the PAT liquid analysis measurement calibration). If further types of PAT measurements are defined in the CDD in the future, the corresponding properties of these measurement types will also be permitted.
