Detection & conditioning
The Blue Ring Tester is a simple, low-cost device that applies a short pulse to a coil and then counts the number of decaying oscillations (ringing). A good coil will produce many oscillations; a coil with a shorted turn will produce very few because the short absorbs the energy.
The Blue Ring Tester is a specialized diagnostic tool used primarily for "ringing" a coil. When you apply a pulse to an inductor, it should resonate (or ring) if it is in good condition. If the component has a shorted turn, the magnetic field collapses almost instantly, dampening the resonance. blue ring tester schematic diagram exclusive

The Blue Ring Tester is an essential, cost-effective tool for any electronics enthusiast or professional who regularly works with flyback transformers and switch-mode power supplies. Its simple design and intuitive LED display make it easy to build yourself. For more insights and community discussions, you can explore the following active electronics forums where enthusiasts and professionals share their experiences:
A: No. An LC meter measures inductance and capacitance. The Blue Ring Tester measures Q factor and loss—a different parameter. When you apply a pulse to an inductor,
The decaying AC ringing waveform is fed into a high-speed voltage comparator (like the or an internal microcontroller comparator).
The tester is widely available as a DIY kit or pre-assembled unit: Anatek Blue Ring Tester Assembly and Review HD
Uses an LM393 comparator or similar op-amp to amplify and "square up" the ringing waveform so it can be counted by the logic section. Key Passive Components:
A single shorted turn absorbs the magnetic energy. The oscillation dampens rapidly, cutting the "rings" short. Exclusive Schematic Diagram Breakdown
