 II Performance

1. Measurable Ζ type coupling transformer.
2. 2 output voltage can be choosen,   large  no-load current transformer can be measured.
3. wide range, ratio can reach max ****0.
4. Calculate tap position automatically.
5. Fast speed, three-phase *8 seconds.
6. Great repeatability, data is automatically saved and store up to *9.
7. Flexible data processing, It can be retrieved, print, transferred to U disk, and delete, upload the PC.
