    RMS magnitude of the selected harmonic. 6.11.4 Fundamental Voltage Fundamental Volts are the nominal component (50/60Hz) of the waveform. The M651 measures the magnitude of the fundamental phase-to-neutral and phase-to-phase volts. These measurements can be used in conjunction with the distortion measurements to obtain the magnitudes of harmonics, in other words, convert from percent to volts.
