Valid values

DAQmx_Val_Voltage 10322 Voltage measurement.
DAQmx_Val_VoltageRMS 10350 Voltage RMS measurement.
DAQmx_Val_Current 10134 Current measurement.
DAQmx_Val_CurrentRMS 10351 Current RMS measurement.
DAQmx_Val_Voltage_CustomWithExcitation 10323 Voltage measurement with an excitation source. You can use this measurement type for custom sensors that require excitation, but you must use a custom scale to scale the measured voltage.
