BEINME Harmonic Distortion Analyzer 10Hz1kHz

Description: HDM210 is a harmonic distortion meter, which mainly detects the ratio of the fundamental wave to the 3rd harmonic of the sine wave signal. Most harmonic problems are caused by the 3rd harmonic. Since the 3rd harmonic is the second highest energy of the fundamental component. Therefore, all we are concerned with is finding the 3rd harmonic distortion using Equation 1.THD = V3/V1*100% (1) Notes: V1: Fundamental; V3: 3rd Harmonic; THD: Harmonic Distortion; 2. Product application: ● Harmonic distortion meter; ● Frequency meter; 3.
