How It Works
The Upgraded W01 injects a controlled AC signal into the coil or circuit trace and measures the resulting magnetic field. Advanced algorithms calculate inductance and instantly flag anomalies such as shorted turns, open circuits, or degraded windings. The integrated fault detector then scans the PCB, highlighting the exact location of the defect on the LCD screen.
