Diagram Exclusive [verified]: Blue Ring Tester Schematic

The Ultimate Guide to the Blue Ring Tester: Exclusive Schematic Diagram and In-Depth Analysis

Introduction: What is a Blue Ring Tester?

In the world of electronics repair, few tools inspire as much curiosity—and confusion—as the Blue Ring Tester. For decades, technicians repairing switch-mode power supplies (SMPS), flyback transformers (LOPT), and deflection yokes have struggled with a common problem: How do you test a coil or transformer for shorted turns without expensive equipment?

2. The Calibration Trimpot (RV1)

Older schematics omit the calibration trimpot entirely. Without RV1, the tester is unreliable for different inductance ranges. Our schematic includes a 10kΩ trimpot in series with R5. Calibration procedure: The Ultimate Guide to the Blue Ring Tester:

The Blue Ring Tester is a diagnostic tool for identifying short-circuited turns in high-Q inductive components, largely based on Bob Parker's original Dick Smith Electronics K-7205 design. An updated version, which features specific schematic details like the CD4015BE shift register and optimized R7 resistance, is currently manufactured by Anatek.
