Data Type: float64
Description: 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 Initial Bridge Ratio, NI-DAQmx coerces this property to Initial Bridge Ratio times Actual Excitation Value. This property is set by DAQmx Perform Bridge Offset Nulling Calibration. If you set this property, NI-DAQmx coerces Initial Bridge Ratio to the value of this property divided by Actual Excitation Value. If you set both this property and Initial Bridge Ratio, and their values conflict, NI-DAQmx returns an error. To avoid this error, reset one property to its default value before setting the other.

You can get/set/reset this property using:
