Harmonic distortion analyzer AC power harmonic analyzer 10Hz ~ 1kHz Overview: HDM210 is a harmonic distortion analyzer, the ratio of the major fundamental sine wave signal detection and 3rd harmonics. Most of the harmonics from the third harmonic problems caused. Because of the 3rd harmonic of the fundamental component of the second highest energy. Therefore, we are concerned only found using Equation 1 3rd harmonic distortion. THD = V3 / V1 * 100% (1) Notes: V1: Fundamental; V3: 3 harmonics; THD: harmonic distortion; Application: Harmonic distortion device; Frequency meter; Technical parameters: No. Item Parameter Unit Remark A measurement frequency range 10 ~ 1000 Hz The most significant measure 10.0Vpp 2 AC signal voltage range of 1 ~ 10 VDC 3 measuring 0.1 to 100.0% distortion 4 7 ~ 12 VDC operating voltage 5 Operating current <50 mA 6 size 56 * 45 * 20 mm length X width X height Interface Display and operating instructions: (1) Key Description: SEL: Select the monitoring parameters; LCD font: Notes: # 1,1st = 0.0 show the fundamental values; 2,3st = 0.0 show the 3rd harmonic value; 3, THD = 0.0% harmonic distortion display 4, Fre = 0Hz shows the measured frequency Potentiometer RW1 Function: Adjusts the moderate voltage signal to the instrument measurements. Light-emitting diode LED: When the input voltage is too high to measure lit. Wiring P1 connection definition: No. Symbol Meaning 1 VDD positive power supply module (7V ~ 12V) 2 GND negative power supply module P2 connection definition: No. Symbol Meaning 1 AC AC signal input (maximum input 10Vpp) 2 AC AC signal input Package including 1xHDM210 is a harmonic distortion analyzer Payment We accept the payment via PayPal only.
