Blue Ring Tester Schematic Diagram Exclusive New! Jun 2026

: The tester typically features 8 LEDs that represent the quality (Q) factor of the component: No Lights : Direct short circuit. Red LEDs : Low Q (Likely bad). Yellow LEDs : Medium/Marginal Q. Green LEDs : High Q (Likely good). How to Use the Tester

SMPS transformers often fail with a single shorted turn due to overheating. The resistance change is immeasurable with a DMM. The Blue Ring Tester detects this in seconds. blue ring tester schematic diagram exclusive

A single shorted turn in a transformer acts like a secondary winding with zero resistance. It draws massive current, overheats the core, and kills the circuit. To find this, you need to analyze the coil’s and Q factor (quality factor). The Blue Ring Tester solves this by hitting the coil with a short, sharp pulse and analyzing the damped sinusoidal wave (the "ring") that results. : The tester typically features 8 LEDs that
