This tester is an innovative product that overcomes the shortcomings of traditional variable ratio bridge testing. The screen adopts a large high-resolution LCD display and is powered by lithium batteries, making it convenient for on-site use. The product is mainly used for transformer ratio group testing, PT and CT ratio polarity testing, with fast testing speed and high accuracy.

▶ Equipped with lithium battery or 220V AC power supply, adaptive, capable of continuous testing of over 100 transformer ratio groups on a single charge, the testing process is simple and convenient.

▶ Equipped with blind testing function, which means conducting ratio and group tests without knowing the high and low voltage connection methods.

▶ On the basis of testing conventional transformers, Z-type transformers, and PT samples, CT variable ratio polarity testing function has been added, which has a wider range of applications.

▶ Wide measuring range and high accuracy, with a variable ratio measurement range of up to 10000, and a testing accuracy of 0.3% at high values of 10000.

▶ Equipped with complete protection functions such as reverse connection protection and output short-circuit protection.

▶ The 5.6-inch large industrial grade high brightness color LCD screen displays clearly and visibly even in strong sunlight.

▶ Equipped with a thermal printer for easy data printing.

▶ Equipped with local storage and USB storage, convenient for data storage.
