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/ 60HZ.

3: Equipped with safety protection device to lock each other with 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) can be carried out; the withstand voltage test between the voltage and the current (U/I); the withstand voltage test Ia between the A-phase current and the C-phase current /Ic (optional)

5: A leakage current tester is set up 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 normal testing of other epitopes.

6: When the epitope is broken down, it has a sound and light alarm prompt.

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)
