Toggle, the display is clear under sunlight.

2. The software can set the test voltage, protection voltage and test time, and the test can be completed automatically.

3. With overvoltage protection, overcurrent protection, disconnection protection, non-zero start, ground detection and overload protection

protection and other functions.

4. It has the functions of clock calendar display and environmental temperature and humidity detection.

5. It can store 200 sets of test data, the data can be directly printed or exported to the U disk, and the data can be exported in TXT format

format, the data is in table format and can be printed directly on the computer.

6. RS232 communication interface with high voltage isolation, which can be controlled remotely.

7. The high-end anti-shock ammeter and the host have wireless communication functions, and the data of the ammeter can be directly stored on the host

on display.

8. It has the functions of automatic test, 10 step test, manual test and zinc oxide arrester automatic test.

9. It has the function of completing the high-voltage leakage current test of the two-section arrester with a single boost.

10. Unique capacitive test product automatic boost mode, avoiding interruption of test due to over-current.

11. Digital potentiometer is adopted, with 7 step voltage options:

60-160kV equipment (0.05kV, 0.1kV, 0.2kV, 0.5kV, 1.0kV, 2.0kV, 5.0kV)

200-350kV equipment (0.1kV, 0.2kV, 0.5kV, 1.0kV, 2.0kV, 5.0kV, 10kV)

12. Wide power supply voltage input: AC165V-245V, 50-60HZ.
