Specifies if NI-DAQmx divides the measurement by the excitation. You should typically set this property to TRUE for ratiometric transducers. If you set this property to TRUE, set AI.Max and AI.Min to reflect the scaling.

For example, if you expect to acquire a voltage between -5 and 5, and you use an excitation of .10 volts to scale the measurement, set AI.Min to -50 and set AI.Max to 50. If you set AI.Bridge.Cfg to No Bridge, this property has no effect on the measurement.
