The main functions and features:

1, Automatic variable ratio measurement function, do not need to set any parameters, can be automatically completed three phase transformation ratio and the category of measurement, easy operation, just a button.

2, Can automatic measurement, three-phase continuous measurement, single-phase measurement transformer voltage ratio, and can calculate the ratio error.

3, Measuring various kinds of transformer of coupling group Y/Y, Y/d, D/y and D/d, ZN/y, ZN/d, etc.

4, Measuring Z-type transformers from any angle (non-whole points).

5, Measuring transformer connection group label and polarity.

6, Automatic track transformer on load tap changers position, and automatically indicate the current tapping point.

7, Automatic protection function perfect and reliable, to ensure equipment is in good under the various abnormal conditions.

8, Small volume, light weight, accurate measurement, speed is fast (three phase measurement just 10 seconds)

9, Can be stored (40 times) or print all measurement results, the instrument was built-in do not power-fail memory, can be stored for a long time measurement data and can print and refer at any time.

10, Full Chinese characters menu and operation tips, intuition and convenient.

11, Do not power-fail the calendar clock function.
