Introduction
Multimeter can accurately measure the three-phase power distribution system for all common power parameters:three-phase voltage, phase current, active power, reactive power, power factor, line frequency, active power, reactive power, and with communication interface and pulse output functions.
Working principle
Signal acquisition: Obtain physical quantity signals (such as voltage, current, temperature, pressure, etc.) through built-in sensors (such as current/voltage transformers, temperature probes, pressure sensors, etc.).
Signal processing: Convert analog signals into digital signals (ADC conversion), filter, calibrate and calculate through microprocessors to eliminate interference errors.
Functional operation: Calculate derived parameters (such as power, energy consumption, frequency, flow, etc.) according to preset algorithms, support alarm threshold judgment or data storage.
Output display: Display data intuitively through LCD/OLED screen, and support communication interface (RS485/4-20mA/Wi-Fi, etc.) to transmit to the host computer or cloud platform.
