<SignalCalibrationIdentifier> is a container object for the calibration parameters of the signal. It is inherited from AnalogSignalType and has an additional interface reference to IPhCalibrationType to add pH signal specific calibration variables. Since it is a placeholder, an instance of PhSignalType 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 IPhSignalConditionSetType to add pH signal specific condition variables.
The components of PhSignalType have additional references which are defined in Table 135.
