8930 / 8730C faces the energy saving market of electrical and electronic equipment, and is widely used in various fields from research and development to production lines. In home appliances and OA (Office Automation) equipment, industrial equipment, hybrid / electric vehicle batteries, solar / wind power generation related equipment and other electronic fields and electromechanical-integration field, power analyzers are widely used in product development, performance testing and quality Management of power consumption in processes such as management. In these fields, in the face of rising awareness of environmental protection and energy saving and lack of electricity, further energy saving is required in product design. In order to quickly put products with excellent energy-saving performance on the market, in the development and production of manufacturing plants, it is required to improve work efficiency. Power meters with higher measurement efficiency have become the general trend. High-speed measurement of various items can simultaneously measure voltage, current, power, accumulated energy conventional measurement items and harmonic analysis that need to perform calculations and other measurement items. The data update rate is faster and the measurement efficiency is greatly improved.
