  • Page 11: Crest Factor

    4-3 Crest Factor The CR (crest factor) indicates the peak value of a signal by dividing it by its root-mean-square value. With most common waveforms such as sinusoidal wave and chopping wave, the crest factor is relatively low. With waveforms similar to low duty cycle pulse trains, the crest factor is high.
  • Page 12 [5] MEASURING PROCEDURE WARNING 1. Do not apply an input signal exceeding the maximum rated input of each function. 2. During measurement, do not change the function switch. 3. During measurement, do not hold a place beyond the barrier of the meter or the test pin side of the flange of the test leads.
