The instrument is a rapid tester integrating the functions of magnetic aid method, three-phase test (Yn, Y, △) and degaussing. It is an ideal device for measuring the DC resistance of large power transformers. The screen adopts a true-color large-screen high-resolution LCD screen, and the touch and shuttle knob operation is convenient for on-site use. With English menu prompt function, the operation is simple and intuitive, and all direct resistance test items can be completed in one connection, with fast test speed, high accuracy and wide range.
