  • Page 14: True Rms Measurement

    TM- 2012/2013/3012/3014 6. TRUE RMS MEASUREMENT The meter measures the true RMS value of AC voltages and currents. In physical terms, the RMS (root-mean-square) value of a waveform is the equivalent DC value that causes the same amount of heat to be dissipated in a resistor. True RMS measurement greatly simplifies the analysis of complex AC signals.

  • Page 15: Waveform Comparison

    TM- 2012/2013/3012/3014 8. WAVEFORM COMPARISON Table 1.illustrates the relationship between AC and DC components for common waveforms, and compares readings for true RMS meters and average-responding meters. For example, consider the first waveform, a 1.414V (zero-to-peak) sine wave. Both the RMS-calibrated average-responding meters display the correct RMS reading of 1.000V(the DC component equals 0).
