Product Features
1. The device is equipped with over-pressure, over-current, zero-start, and system detuning (flash drop) protection functions. The over-pressure and over-current protection values can be set according to user requirements, and the flash drop protection action can be triggered during the flash drop test, with the flash drop voltage value recorded for analysis.
2. The entire unit is extremely lightweight, with no piece weighing more than 40kg, making it convenient for on-site use.
3. The device features four operating modes for flexible selection based on site conditions, enhancing testing speed. The modes are: Full-Automatic Mode, Manual Mode, and Automatic Tuning Manual Boost Mode.
4. Capable of storing and printing data remotely; the stored data is numbered, which conveniently aids users in identification and search.
5. During automatic frequency scanning, the starting frequency can be set within the specified range, with options for scanning up or down. Additionally, a large LCD screen displays the scanning curve, allowing users to easily visualize if a resonance point has been found.
6. Utilizes DSP platform technology, allowing for easy addition or removal of features and upgrades based on user needs, and also enhances the user-friendly nature of the human-machine interaction interface.
