Intelligent and Efficient Testing Solution This series of testers features a 4.3-inch TFT color LCD screen with an intuitive and easy-to-understand interface. It supports programmable storage of 105 test files, each capable of setting 25 consecutive test steps to meet the automated testing needs of complex scenarios. Equipped with rich interfaces such as RS232C, USB, and HANDLER, it enables computer remote control, data export, and quick import of test plans, seamlessly connecting production line and laboratory scenarios. Parameters such as voltage rise/fall time and test delay can be precisely adjusted (0.1s-999.9s). Combined with the optional multi-channel module, continuous testing of multiple measurement points can be completed without repeated wiring, significantly improving testing efficiency. With a compact design (215×143×405mm) and a weight of only about 12kg, it balances portability and stability, making it an ideal testing partner for electronic manufacturing, quality inspection, R&D verification, and other scenarios.
