Data Type: bool32
Description: 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 Maximum Value and Minimum Value 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 Minimum Value to -50 and set Maximum Value to 50. If you set Configuration to DAQmx_Val_NoBridge, this property has no effect on the measurement.

You can get/set/reset this property using:
