The tester identifies shorted turns in coils that standard ohmmeters cannot detect. It works by injecting a low-voltage pulse (approx. 600–650mV) into the component and counting how many times the circuit "rings" (oscillates) before the signal decays. A higher number of lit LEDs indicates a higher Quality (Q) factor and a healthy component. 1. Technical Schematic Analysis The circuit, originally designed by Bob Parker
