Blue Ring Tester Schematic Diagram Exclusive

Connect a known good inductor. The green LED should illuminate steadily. Short one turn of wire around the core. The red LED should now light.

The "Blue Ring Tester" works by applying a fast voltage pulse to an inductor and counting the number of resulting "rings" (decaying AC oscillations).

A acts as a secondary winding with a dead short. This dramatically reduces the Q factor. The ringing stops after just 1 or 2 cycles instead of 10 or more. blue ring tester schematic diagram exclusive

The Blue Ring Tester powers the component independently, making it safe to use on dead equipment.

In the world of electronics repair and troubleshooting, identifying faulty components—specifically inductors, flyback transformers, and switching transformers—can be a daunting task. A traditional multimeter often fails to detect shorted turns, which are the most common cause of failure in these components. Enter the . Connect a known good inductor

Enter the Blue Ring Tester. This brilliant, low-cost device uses a pulse ringing test to identify shorted turns instantly. Today, we are providing an along with a component-level explanation of how it works.

The coil under test (Lx) and C2 (10nF) form an LC tank. When the pulse ends, the energy stored in the magnetic field of Lx collapses, causing the tank to resonate at its natural frequency: ( f = \frac12\pi\sqrtLC ). The red LED should now light
