<SignalCalibrationIdentifier> is a container object for the calibration parameters of the signal. It is inherited from AnalogSignalType and has an additional interface reference to IConductivityCalibrationType to add conductivity signal specific calibration variables. Since it is a placeholder, an instance of ConductivitySignalType can have several calibration objects.
SignalConditionSet is a container object for the condition parameters of the signal. It is inherited from AnalogSignalType and has an additional interface reference to IConductivitySignalConditionSetType to add conductivity signal specific condition variables.
The components of ConductivitySignalType have additional references which are defined in Table 139.
