1、Voltage, current, time, status information, and prompt information are displayed on a 7-inch large LCD screen, with clear and intuitive readings;
2、Full Chinese interface, simple and clear operation, suitable for various application scenarios;
3、Touch button operation, all functions can be set through buttons, improving the safety and reliability of the product;
4、The fully digital calibration method eliminates outdated potentiometer adjustments, making on-site use extremely convenient and accuracy easy to control;
5、The button directly sets the transformation ratio of the test transformer. When connecting testers with different voltage levels, the application is flexible and flexible, truly achieving that a control box can be used in conjunction with multiple transformers;
6、Status reminder function, guided operation, can be proficiently operated even without a manual;
7、Automatic timing function. During automatic control, when the voltage automatically rises to the set value, the equipment will start timing automatically. When the timing time is up, the test results will be displayed, and the equipment will automatically return to zero;
8、Manual timing function. When manually controlled, the timer can be manually started. When the withstand voltage time is reached, the equipment will automatically return to zero position;
9、Manual control mode, similar to the traditional electric lifting/lowering method, the lifting/lowering is controlled by buttons, and the equipment automatically determines the upper/lower limit, with overvoltage protection;
10、The boosting speed can be set, with a default of 1kV/S;
11、The combination of hardware and software anti-interference technology ensures stable performance and strong anti-interference ability.
Enterprise products in strict accordance with international and national standards and rules of industry production, through the national, provincial and municipal electric power research institute and electric power authorities detection, measuring center, fully passed the ISO9001 international quality management system certification, the licence for manufacturing measuring instruments of the People's Republic of China, GB/T19001-2016 quality management system requirements, GB/T24001-2016 environmental management system requirements, GB/T45001-2020 occupational health and safety management system requirements.
