This instrument is a new generation rapid testing device that integrates magnetic assistance testing, three-phase testing (Yn, Y, △), and demagnetization functions. It is an ideal equipment for measuring the DC resistance of large power transformers. The screen adopts a true color large screen high-resolution LCD display, with touch control and shuttle knob operation, making it convenient for on-site use. It has a Chinese menu prompt function, easy and intuitive operation, and can complete all direct resistance test items in one wiring. The testing speed is fast, the accuracy is high, and the range is wide.

▶ For Yn, Y, and △ windings, three-phase measurement can be used to test and calculate the three-phase unbalance rate.

▶ Test the high output current of the power supply at 40A, with a testing range of 0-25k Ω, meeting the testing requirements of the vast majority of transformers; And it integrates magnetic assistance and demagnetization functions to meet various on-site testing needs.

▶ The testing process automatically calculates the resistance value change rate for 5 seconds, 15 seconds, and 30 seconds, which can assist the testing personnel in judging the stability of the test data to prevent misreading of the data.

▶ The instrument has multiple protection functions such as 380V misconnection protection, back electromotive force protection, wire breakage protection, and power-off protection, as well as an alarm function for ungrounded grounding wire.

▶ The instrument is equipped with a thermal printer, which stores 200 pieces of data and supports massive storage on a USB drive.

▶ 7-inch true color large screen display, fresh and simple display style design, full touch and one click shuttle operation, creating a comfortable and convenient human-machine interaction experience for you.
