A true-RMS device (RMS = root mean square) is one of three tools that can measure alternating current (ac) or ac voltage: True-RMS digital multimeters (or clamp meter) Average-responding digital multimeter (or clamp meter) Oscilloscope; Only the first two tools are commonly used, and both can accurately measure standard (pure ac) sinusoidal ...

True RMS Voltmeter – Complex waveform are most accurately measured with an rms voltmeter. This instrument produces a meter indication by sensing waveform heating power, which is proportional to the square of the rms value of the voltage.
