Blue Ring Tester Schematic Diagram | Exclusive

After analyzing this , we compared it against a commercial $500 LCR meter. The results were surprising:

The circuit is elegant in its simplicity, typically based on a comparator IC like the or a microcontroller like the PIC16F628A . The Core Components blue ring tester schematic diagram exclusive

The is a specialized diagnostic tool designed to test high-Q (low loss) inductive components, such as flyback transformers and SMPS transformers, by measuring their "ringing" response. Originally designed by Bob Parker and popularized through kits by AnaTek , the circuit uses a fast voltage pulse to excite a resonant tank circuit, where the number of resulting oscillations—the "rings"—indicates the component's quality (Q) factor.
