Parameter

Name	Type	Description
nOversamples	UDINT	Oversampling factor
fOffsetVoltage	LREAL	Indicates a user-defined offset for the voltage scaling.
fGainVoltage	LREAL	Indicates a user-defined gain factor for the voltage scaling.
fOffsetCurrent	LREAL	Indicates a user-defined offset for the current scaling.
fGainCurrent	LREAL	Specifies a user-defined gain factor for the current scaling.
fFactorCurrentTransformer	LREAL	Current transformer factor. This is calculated from the input current and output current.
