Short Name: AI.Bridge.InitialRatio

Property of DAQmx Channel

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 AI.Bridge.InitialVoltage, NI-DAQmx coerces this property to AI.Bridge.InitialVoltage divided by AI.Excit.ActualVal. If you set this property, NI-DAQmx coerces AI.Bridge.InitialVoltage to the value of this property times AI.Excit.ActualVal. If you set both this property and AI.Bridge.InitialVoltage, and their values conflict, NI-DAQmx returns an error. To avoid this error, reset one property to its default value before setting the other.
