Enums

Enums used in NI-DMM

ADCCalibration

class nidmm.ADCCalibration

AUTO

The DMM enables or disables ADC calibration for you.

OFF

The DMM does not compensate for changes to the gain.

ON

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

AcquisitionStatus

class nidmm.AcquisitionStatus

RUNNING

Running

FINISHED_WITH_BACKLOG

Finished with Backlog

FINISHED_WITH_NO_BACKLOG

Finished with no Backlog

PAUSED

Paused

NO_ACQUISITION_IN_PROGRESS

No acquisition in progress

ApertureTimeUnits

class nidmm.ApertureTimeUnits

SECONDS

Seconds

POWER_LINE_CYCLES

Powerline Cycles

AutoZero

class nidmm.AutoZero

AUTO

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

OFF

Disables 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.

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.

CableCompensationType

class nidmm.CableCompensationType

NONE

No Cable Compensation

OPEN

Open Cable Compensation

SHORT

Short Cable Compensation

OPEN_AND_SHORT

Open and Short Cable Compensation

DCNoiseRejection

class nidmm.DCNoiseRejection

AUTO

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

NORMAL

NI-DMM weighs all samples equally.

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.

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.
