10.1 inch 1280×800 capacitive touch screen
Graphical pin association setting page, so that wiring is no longer a problem
Lk setting does not need to input the leakage inductance pin, which is more intuitive
Enhanced balance scanning function, from 5 points to 10 points
Range switching adopts electronic switch, fast speed, long life, no noise
Optional LCR function
Approximately 100M setting file storage space in the machine, and massive U disk setting file storage capacity
Provide host computer to support early model file format conversion to ensure compatibility
A. Revolutionary Design
Featuring a dual-CPU architecture running on a Linux-based operating system—and supporting input via touchscreen, keyboard, and mouse, along with built-in multilingual help functions—this device delivers an unparalleled user experience. It significantly lowers the barrier to entry for operators while boosting testing efficiency several-fold.
B. Large 10.1-inch Screen: Streamlined Setup and Simplified Operation
Equipped with a 10.1-inch touchscreen display boasting a 1280 x 800 resolution, this large interface offers distinct advantages: it consolidates all critical settings—including transformer pin assignments, test parameters, pin series/parallel configurations, and sorting criteria—onto a single screen. Users can interact directly via touch or through a keyboard and mouse, ensuring that operations are not only rapid but also visually uncluttered and organized.
