1. Lithium battery power supply or 100-240V AC power supply is self-adaptive. After one charge, more than 100 transformers can be continuously tested in the ratio group. The test process is simple and convenient.
2. It has the function of blind measurement, that is, to perform variable ratio and group test when there is no connection between high and low voltage.
3. Based on the test of conventional transformer, Z-type transformer and PT sample, the polarity test function of CT variable ratio is added, and the application field is wider
4. Wide range and high accuracy, the variable ratio measurement range can reach 10,000, and the test accuracy can be guaranteed 0.3% when the maximum value is 10,000.
5. It has perfect protection functions such as reverse connection protection and output short circuit protection.
6. 5.6-inch super industrial high-brightness color LCD screen, still visible under strong sunlight.
7. equipped with printer, facilitate data printing
8. It can be stored locally and on USB memory.
