True RMS: In measuring the AC voltage / current is used, the average measured value at much multimeters. This measurement is only correct when the wave of the AC voltage / current is sinusoidal. The Extech EX542 takes into account different waveforms and therefore measured using True RMS. With this method the real effective value is measured, which provides a higher accuracy
