2. Primary Functions and Technical Specifications

2.1 Main Features

1）、Voltage, current, time, status information, and prompt messages, etc.7-inch large-screen LCD display, offering clear and intuitive readings.

2）、The full Chinese interface is easy to operate and clear, adaptable to various application scenarios.

3）、TouchscreenOperation, all features are accessibleTouchscreenEstablished, enhancing product safety and reliability.

4）、All-digital calibration method, discarding the outdated potentiometer adjustments, offers extreme ease of use on-site and precision that's easy to control.

5）、Directly set the transformer ratio on the touch screen, offering flexibility in connecting different voltage level testers, truly enabling a single control console to be paired with multiple transformers. 

6）、Status reminder feature with full Chinese guided operation, allowing for proficient operation even without a manual. 

12）、Manual timing function: When manually controlled, the timer can be manually started. Upon reaching the pressure resistance time, the device automatically returns to zero. 

13）、Manual Control Mode, a mode similar to traditional electric lifting/Pressure reduction methods: up/down controlled by buttons; the device automatically detects upper/lower limit positions; with overvoltage protection.

14）、The boost-up speed can be set; default1KV/S；

15）、Utilizing a combination of hardware and software anti-interference technology, the performance is stable and highly resistant to interference.
