Product IntroductionProduct Introduction
This instrument is used for measuring three-phase electrical parameters, analyzing the correctness of CT wiring in protection circuits, and detecting the imbalance of three-phase electrical voltage and current. It can achieve high-precision measurement of three-phase electrical parameters such as voltage, current, phase angle, frequency, power, and power factor. What's even more unique is that it can analyze the correctness of CT wiring and check the power balance of power lines. And it has the function of calculating electrical energy.
This instrument is designed with a high-speed ARM processor as the lower computer for measuring electrical parameters. It has a fully graphical interface, true color display, and a user-friendly touch screen operation interface. The instrument is easy to carry and has powerful functions.
Product nickname: Multi functional electricity tester, Multi functional three-phase electricity tester, Electricity tester, Three phase multi-functional electricity tester, Multi functional electricity tester
