It helps detect loose connections, poor welding, missing turns, and hidden defects. The tester adopts microcontroller control with automatic discharge, multiple protection functions, and intelligent power management to ensure safe, stable, and energy-efficient operation. It also supports temperature conversion for copper and aluminum windings. It features a 7-inch touch LCD with bilingual interface, data storage of 1000 results, built-in printer, and Bluetooth/USB/RS232 communication. Mobile app control further improves convenience in field testing and data management.
