Features of Transformer Turns Ratio Tester with Battery Blind Test Function:
1. Automatically measures the connection group.
2. Automatically changes the group, can directly measure the turns ratio of single-phase, three-phase transformers and instrument transformers.
3. Automatically switches phase sequence.
4. Automatically switches range.
5. Automatically calibrates the meter.
6. After inputting the standard turns ratio, it can automatically calculate the relative error.
7. After one measurement is completed, the test voltage is automatically cut off.
8. The measurement results are automatically saved, test data can be printed, and 20 historical measurement data can be stored.
