  • Page 39: True Rms Ac Measurements

    4.Measurement Tutorial True RMS AC Measurements The AC measurement of the multimeter has true RMS response. Power dissipated in a resistor is proportional to the square of an applied voltage, independent of the wave shape of the signal. This multimeter accurately measures true rms voltage or current, as long as the wave shape contains negligible energy above the meter’s effective bandwidth.

  • Page 40: Loading Errors (Ac Voltage)

    4.Measurement Tutorial Loading Errors (AC Voltage) In the AC voltage function, the input impedance of the multimeter appears as a 1 MΩ resistance in parallel with 100 pF of capacitance. The cabling that you use to connect signals to the multimeter also adds capacitance and loading. The table below shows the multimeter's approximate input resistance at various frequencies.

  • Page 41: Crest Factor Errors (Non-Sinusoidal Inputs)

    4.Measurement Tutorial Crest Factor Errors (non-sinusoidal inputs) A common misconception is that because an AC multimeter is true RMS, its sine wave accuracy specifications apply to all waveforms. Actually, the shape of the input signal dramatically affects measurement accuracy. A common way to describe signal wave shapes is “crest factor”.
