Blue Ring Tester Schematic Diagram Exclusive Now

The tester connects in parallel with the inductor under test, forming a resonant circuit with an internal capacitor.

Absorbs the energy instantly (lighting up few or no LEDs). Exclusive Schematic Diagram Analysis blue ring tester schematic diagram exclusive

Most generic testers use a simple analog decay circuit. The "Blue" version (originally popularized by Bob Parker and Anatek) uses a specific . This ensures that the difference between a good transformer and a "slightly bad" one is visually obvious, rather than a subtle flick of a needle. DIY Tips for Builders The tester connects in parallel with the inductor

To get an accurate "Blue" reading, the internal resonance capacitor must be high quality (Polypropylene is best). The "Blue" version (originally popularized by Bob Parker

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.

If you build this from a schematic, calibrate it using a known-good flyback transformer. You want the full "Blue" range to light up on a healthy, high-inductance component.
