If you work with power supplies, CRT monitors, or motor drives, you know that a "shorted turn" in a transformer or inductor is a technician's nightmare. A standard multimeter will show perfect continuity, but the component will fail under load.
Absorbs the energy instantly (lighting up few or no LEDs). Exclusive Schematic Diagram Analysis blue ring tester schematic diagram exclusive
The tester connects in parallel with the inductor under test, forming a resonant circuit with an internal capacitor. If you work with power supplies, CRT monitors,
The Blue Ring Tester is a specialized "in-circuit" diagnostic tool. It performs a (or Q-test). By injecting a pulse into a coil, it measures how many times the energy "echoes" or "rings" before dying out. Healthy Coil: Rings many times (lighting up all the LEDs).

Attach the tester leads across the primary winding of the transformer or the inductor. Read the LEDs:
