Specifies in volts the output voltage of the bridge while not under load. NI-DAQmx subtracts this value from any measurements before applying scaling equations. If you set AI.Bridge.InitialRatio, NI-DAQmx coerces this property to AI.Bridge.InitialRatio times AI.Excit.ActualVal. This property is set by DAQmx Perform Bridge Offset Nulling Calibration. If you set this property, NI-DAQmx coerces AI.Bridge.InitialRatio to the value of this property divided by AI.Excit.ActualVal. If you set both this property and AI.Bridge.InitialRatio, and their values conflict, NI-DAQmx returns an error. To avoid this error, reset one property to its default value before setting the other.
