Valid values

DAQmx_Val_FullBridge 10182 Sensor is a full bridge. If you set Use Excitation For Scaling to TRUE, NI-DAQmx divides the measurement by the excitation value. Many sensors scale data to native units using scaling of volts per excitation.
DAQmx_Val_HalfBridge 10187 Sensor is a half bridge. If you set Use Excitation For Scaling to TRUE, NI-DAQmx divides the measurement by the excitation value. Many sensors scale data to native units using scaling of volts per excitation.
DAQmx_Val_QuarterBridge 10270 Sensor is a quarter bridge. If you set Use Excitation For Scaling to TRUE, NI-DAQmx divides the measurement by the excitation value. Many sensors scale data to native units using scaling of volts per excitation.
DAQmx_Val_NoBridge 10228 Sensor is not a Wheatstone bridge.
