1. One-piece and split-body structures.

2. Equipped with SYH12 special program-controlled electric energy meter withstand voltage meter, using DDS signal source, PWM digital power amplifier, 10-bit A/D conversion, voltage rising and falling function; output frequency 

50HZ/60HZo

3. Equipped with safety protection devices, which are mutually locked with the high-voltage output. A warning light is installed above the device.

4. The test between the voltage and current between the shell and the auxiliary terminal (UI/shell auxiliary); the withstand voltage test between the voltage and the current (U/I) can be carried out.

5. A leakage current tester is set separately for each epitope, with independent withstand voltage cutoff, leakage current detection, and breakdown alarm. The breakdown of a certain epitope will not affect the positive state of other epitopes. 

Test often.

6. When the epitope is broken down, it has sound and light prompts.

7. By switching the test function switch, various tests of the electric energy meter can be completed at one time.

8. The RS232 communication port is reserved, which is convenient for the completion of the test program control, and the test results are uploaded to the computer for data management. (optional function)
