1. Powered by lithium battery or 220V AC power supply with automatic adaptation. A single charge allows continuous testing of turns ratio and vector group for more than 100 transformers, making the testing process simple and convenient.
2. Can test the turns ratio, vector group, and polarity of transformers, PT transformers, Z-type transformers, etc.
3. Wide range and high accuracy: the turns ratio measurement range can reach 10000, and when the value is 10000, the test accuracy is guaranteed to be 0.3%.
4. Equipped with comprehensive protection functions such as reverse connection protection and output short-circuit protection.
5. 5.6-inch large industrial-grade high-brightness color LCD screen, still clearly visible under strong light.
6. Equipped with a thermal printer for convenient data printing.
