To overcome these offset voltages, you can use offset-compensated ohms.This feature is only available for resistance measurements or when the smu.measure.unit is set tosmu.UNIT_OHM.Examplesmu.measure.func = smu.FUNC_RESISTANCEsmu.measure.sense = smu.SENSE_4WIREsmu.measure.offsetcompensation = smu.ONsmu.source.output = smu.ONprint(smu.measure.read())smu.source.output = smu.OFFSets the measurement function toresistance. Set the instrument for 4-wiremeasurements and turn offset compensationon. Turn on the source, make ameasurement, and turn the source off.Example output:81592000Also seeNone
