SignalConditionSet is a container object for the condition parameters of the signal. It is inherited from AnalogSignalType and has an additional interface reference to INonDispersiveInfraredSignalConditionSetType to add NDIR signal specific condition variables. The components of NonDispersiveInfraredSignalType have additional references which are defined in Table 157.
