Coupling
niDMM Configure Waveform Coupling
(niDMM_ConfigureWaveformCoupling)
Configures instrument coupling for voltage waveforms on the NI 4070/4071/4072.
niDMM Configure Current Source
(niDMM_ConfigureCurrentSource)
Configures the current source for diode measurements on the NI 4070/4071/4072.
niDMM Configure Frequency Voltage Range
(niDMM_ConfigureFrequencyVoltageRange)
Specifies the expected maximum amplitude of the input signal for frequency and
period measurements on the NI 4070/4071/4072.
niDMM Configure AC Bandwidth
(niDMM_ConfigureACBandwidth)
Configures the Min Frequency and Max Frequency properties that the DMM uses
for AC measurements.
niDMM Configure Offset Comp Ohms
(niDMM_ConfigureOffsetCompOhms)
Allows the NI 4070/4071/4072 to compensate for voltage offsets in resistance
measurements.
niDMM Configure ADC Calibration
(niDMM_ConfigureADCCalibration)
Allows the NI 4070/4071/4072 to compensate for gain drift since the last external or
self-calibration.
niDMM Configure Auto Zero
(niDMM_ConfigureAutoZeroMode)
Configures the DMM for Auto Zero.
