In the world of electronics troubleshooting, few tools inspire as much curiosity and respect as the . Unlike a standard multimeter, which struggles to find shorted turns in a transformer or a flyback (LOPT), the Blue Ring Tester uses a pulsed energy technique to assess the "ringing" characteristics of an inductor.
The tester is widely available as a DIY kit or pre-assembled unit: Anatek Blue Ring Tester Assembly and Review HD
The tester counts oscillations that exceed a specific threshold. These are then displayed as a "ring count" across the LED bar. LED Feedback: The 8 LEDs typically range from (bad/low Q) to (medium) to (good/high Q). 🛠️ Key Schematic Components blue ring tester schematic diagram exclusive
: Major short circuit. The component has a shorted turn or a severely shorted internal winding. It must be replaced.
Generates a square wave pulse.
Following the above, trace the signal path:
When the short test pulse hits this high-Q circuit, it acts like a sharp tap, injecting a burst of energy. The tuned circuit responds by oscillating or "ringing" at its natural resonant frequency. In a good inductor, this ringing will slowly decay over several cycles, producing a waveform of diminishing amplitude. A poor component, however—one that has shorted turns, a high DC resistance, or other losses—will have a low Q factor and will dampen this oscillation rapidly, producing very few (or zero) rings.

A shorted turn lowers the inductance significantly and increases the damping effect.
A shorted coil causes the ringing to decay so quickly that the comparator only sees one or two zero-crossings. This is sensed by a simple RC network (R4, R6) that charges a capacitor. If the capacitor charges above a threshold (good coil), the green LED lights. If it fails to charge (bad coil), the red LED lights. These are then displayed as a "ring count"
