Description: 1、 Overview: HDM210 is a harmonic distortion meter that mainly detects the ratio of the fundamental wave to the third harmonic of a sine wave signal. Most harmonic problems are caused by third harmonic waves. Because the third harmonic is the second highest energy of the fundamental component. Therefore, our concern is only to find third harmonic distortion using Equation 1. THD = V3/V1*100% (1) Note: V1: fundamental wave; V3: 3rd harmonic; THD: Harmonic distortion; 2、 Product Application: ● Harmonic distortion meter; ● Frequency meter; 3、 Technical parameter table: SN Item Parameter Unit Remarks 1. Measurement frequency range: 10~1000 Hz 2. Measuring voltage range: 1~10 VDC, maximum amplitude: 10.0Vpp AC signal Measurement distortion 0.1~100.0% 4. Working voltage 7~12 VDC 5 Operating current<50 mA Size 56 * 45 * 20 mm L x W x H 4、 Interface display and operation instructions: (1) Key description: SEL: Select monitoring parameters; LCD font: Notes: #1,1st=0.0 shows the fundamental value; 2,3st=0.0 displays the third harmonic value; 3, THD=0.0% shows harmonic distortion 4, Fre=0Hz Display measurement frequency Potentiometer RW1 function: Adjust the appropriate voltage value signal to the instrument for measurement. LED: Illuminates when the input measured voltage value is too high. 5、 Wiring P1 Wiring Definition: Meaning of serial number symbol Power supply positive pole of VDD module (7V~12V) 2 GND module power supply negative pole P2 wiring definition: Meaning of serial number symbol 1 AC AC signal input (maximum input 10Vpp) 2 AC AC signal input
