When conducting high-current tests, correctly connect the working circuit according to the circuit diagram of this product. Based on the magnitude of the output current, select the positions of the large and small range switches appropriately. First, return the voltage regulator to zero, then press the start test button (green). At this point, hold the handle of the voltage regulator and slowly rotate the handwheel clockwise while observing the ammeter until the desired current value is reached. After the test reaches the set value, immediately rotate the handwheel counterclockwise back to zero, press the stop button, and cut off the power supply.



Features:



◆ Date, voltage, current, and time four sets of data are displayed on a blue 5.7-inch large-screen LCD with backlight, providing clear and intuitive readings, simultaneously displaying voltage, current, time, etc., with various data setting functions and a high-speed thermal printer;



◆ The start/stop conditions of the time relay can be arbitrarily set, with a settable time range from 1 second to 9999 seconds;



◆ High-precision sensors and high-performance 14-bit AD acquisition chips;



◆ Touch-type panel button operation, all functions can be set via buttons, enhancing the safety, reliability, and intelligent operation throughout the entire process;



◆ Optional automatic current rise test, manual current rise test, and impact quick-break test, offering flexible and simple operation;



◆ Real-time display of output current and time results, providing intuitive and clear display;



◆ Comprehensive overcurrent protection, with arbitrary setting of target output current value, current upper limit, and current withstand time;



◆ Equipped with grounding detection and zero-return detection functions; the test can only be conducted after grounding and zero-return are confirmed, ensuring safety and reliability;



◆ Approximation-based current rise algorithm, automatically timing the current withstand after reaching the set target output current, and the motor automatically returns to zero after timing ends;



◆ If the set output current upper limit is exceeded, the motor automatically returns to zero and triggers an audible and visual alarm;



◆ Combines hardware and software anti-interference technologies, ensuring stable performance, strong anti-interference capability, and adaptability to harsh electromagnetic environments;



◆ Automatic error diagnosis for easy detection and resolution of issues;



◆ Optional remote communication, door interlock alarm light and bell, open-circuit voltage calibration interface, etc.;



◆ On startup, the company name and other information are displayed, which is beneficial for the promotion and publicity of the company brand;



◆ The product is compact, lightweight, reasonably structured, reliable, and durable.
