Enums

Enums used in NI-DMM

nidmm.ADCCalibration

ADCCalibration.AUTO

The DMM enables or disables ADC calibration for you.

ADCCalibration.OFF

The DMM does not compensate for changes to the gain.

ADCCalibration.ON

The DMM measures an internal reference to calculate the correct gain for the measurement.

nidmm.AutoZero

AutoZero.AUTO

The drivers chooses the AutoZero setting based on the configured method and resolution.

AutoZero.OFF

Disables AutoZero.

AutoZero.ON

The DMM internally disconnects the input signal following each measurement and takes a zero reading. It then subtracts the zero reading from the preceding reading.

AutoZero.ONCE

The DMM internally disconnects the input signal for the first measurement and takes a zero reading. It then subtracts the zero reading from the first reading and the following readings.

nidmm.DCNoiseRejection

DCNoiseRejection.AUTO

The driver chooses the DC noise rejection setting based on the configured method and resolution.

DCNoiseRejection.NORMAL

NI-DMM weighs all samples equally.

DCNoiseRejection.SECOND_ORDER

NI-DMM weighs the samples taken in the middle of the aperture time more than samples taken at the beginning and the end of the measurement using a triangular weighing method.

DCNoiseRejection.HIGH_ORDER

NI-DMM weighs the samples taken in the middle of the aperture time more than samples taken at the beginning and the end of the measurement using a bell-curve weighing method.
