This chapter shows how to measure the internal resistance of the DMM in the voltage/current measurement mode, how to measure the test current of a DMM in resistance measurement mode, how to determine whether the device is a True RMS device and how to obtain the frequency response of your DMM. This chapter contains 7 experiments. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.eninfo:eu-repo/semantics/closedAccessInternal ResistanceMeasurement ModesResistance MeasurementVoltage CurrentBook Chapter61N/A41
