Features:
1. Suitable for mechanical characteristic testing of all models of SF6 switches, GIS combined electrical appliances, vacuum switches, and oil switches produced domestically and internationally.
2. Strong anti-interference capability; can easily test and measure even when the bypass bus of a 500kV substation is live.
3. Universal speed sensor, linear sensor, and rotary sensor are easy and quick to install.
4. One switch operation obtains all data and corresponding waveform graphs of the switch mechanical characteristics.
5. The host can store on-site test data, with a built-in real-time clock for archiving test date and time.
6. Large screen, wide temperature range, direct view, backlit LCD, full Chinese display of all data and graphs; LCD contrast electronically adjustable, power-off memory.
7. Chinese menu operation, easy to use. Built-in printer for quick printing of all data and graphs at any time.
8. Equipped with data analysis management software, can operate with PC; test results can be output to various dot matrix, laser, or inkjet printers for test reports, computerizing field tests.
