<SignalCalibrationIdentifier> is a container object for the calibration parameters of the signal. It is inherited from AnalogSignalType and has an additional interface reference to IAmperometricCalibrationType to add amperometric signal specific calibration variables. Since it is a placeholder, an instance of AnalogSignalType 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 IAmperometricSignalConditionSetType to add amperometric signal specific condition variables.

The components of AmperometricSignalType have additional references which are defined in Table 189.
