to increase sensitivity for low-impedance components like SMPS transformers. Principle of Operation
While the "exclusive" commercial design by (designed by Bob Parker) is sold as a kit, its circuit architecture typically follows a standard operational pattern: blue ring tester schematic diagram exclusive
The is the gold-standard DIY solution for this problem. In this exclusive breakdown, we provide the schematic diagram and explain exactly how this legendary "Q-tester" works. What is a Blue Ring Tester? “Rings = 12”).
This avoids calibration and gives numeric results (e.g., “Rings = 12”). blue ring tester schematic diagram exclusive
