Data Type: float64
Description: Specifies in volts per volt the ratio of output voltage from the bridge to excitation voltage supplied to the bridge while not under load. NI-DAQmx subtracts this value from any measurements before applying scaling equations. If you set Initial Bridge Voltage, NI-DAQmx coerces this property to Initial Bridge Voltage divided by Actual Excitation Value. If you set this property, NI-DAQmx coerces Initial Bridge Voltage to the value of this property times Actual Excitation Value. If you set both this property and Initial Bridge Voltage, 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:
