Feature:
1. Voltage, current, time, status information, and prompt information are displayed on a 10 inch large LCD screen, with clear readings;
2. Full Chinese interface, simple and clear operation, suitable for various application scenarios;
3. Touch based operation, all functions can be pre-set in advance, improving the safety and reliability of the product;
4. Status reminder function, fully Chinese guided operation;
5. Alarm function, closing alarm, 5-second buzzer alarm prompt; Abnormal voltage signal acquisition, buzzing alarm;
6. Emergency stop function, during automatic control, this function can achieve emergency stop of boosting or lowering at any point;
7. Automatic timing function. When the voltage automatically rises to the set value during automatic control, the equipment automatically starts timing. When the timing time is up, the equipment automatically steps down and returns to zero position;
8. Manual control mode, similar to traditional electric up/down mode, is controlled by touch keys, and the device automatically determines the upper/lower limit. It provides protection against high voltage overvoltage and low voltage current, as well as high voltage overcurrent protection;
9. Adopting a combination of hardware and software anti-interference technology, the performance is stable and the anti-interference ability is strong.
10. This instrument has the function of single operation or multiple operation conversion.
Safety precautions:
1. Set up the venue according to relevant regulations, connect the equipment, and in areas where conditions permit, there should be dedicated personnel responsible for safety on site to provide guidance. Connect the grounding terminal of the control panel to the grounding grid, and connect the grounding terminal of the transformer to the grounding grid, ensuring that both grounding terminals are reliably connected to the same grounding grid.
2. Connect the power cord, turn on the power switch, and press the "emergency stop" button if you need to approach the equipment connected to the test transformer, test sample, etc.
3. After the power is turned on. If it is not at zero position, the system will automatically return to zero position.
4. During the experiment, unrelated items are not allowed to be stacked on or around the equipment panel.
5. Please check the power supply voltage before starting up.
When replacing the fuse and accessories, please use the same model as this instrument.
7. This instrument should be moisture-proof and oil proof.
8. Please confirm that the tested equipment has been powered off and disconnected from other live devices during the experiment.
