A portable harmonics measurement instrument performs in-situ self-calibration of its current transducers and their associated measurement channels and of its voltage probes and their associated measurement channels. In-situ self-calibration is performed immediately before making a measurement on the alternating current power distribution grid. In-situ self-calibration is performed by means of a built-in voltage reference source and a built-in current reference source, which generate highly-accurate voltage and current calibration waveforms with harmonic components.
