True RMS digital multimeters

True RMS digital multimeters can accurately measure sinusoidal and non-sinusoidal waveforms.
True RMS: Effective expression of abnormal AC signals
Ordinary multimeters measure RMS indirectly by measuring the average or peak. True RMS multimeters can real-time measure the RMS of various voltage waveforms without considering waveform parameters and distortion.
To obtain accurate measurements for pulse, distortion, frequency conversion, square wave and other non-sinusoidal signals, a true RMS digital multimeter is an ideal choice.
