## Overview

The Blue Ring Tester is a compact, fully assembled tool designed for fast and accurate testing of high Q inductive components such as flyback transformers, SMPS transformers, and deflection yokes. Featuring bright tri-color LEDs for clear Q-level indication and non-polarized test leads for ease of use, it offers enhanced sensitivity for low impedance parts. Backed by a 1-year warranty, it’s the essential diagnostic tool for professionals seeking reliable, on-the-spot component health checks.

## Description

This ring tester is an inexpensive and effective way to test any high Q inductive component. It is especially useful for doing a quick check on flyback transformers, line output transformers and other high frequency inductive components like deflection yoke windings and SMPS transformers. Hi Q = low loss inductive components. A shorted turn or coil will show no rings. A shorted FBT diode will show few or no rings. The LEDs on the left side show the Q of the device being tested, more lights = higher Q, i. e., no lights = short circuit, red = Bad or low Q, yellow = medium Q, green = Good or high Q. Full 1yr warrenty on parts and assembly.

Review: ... what the tester confirms it will do I am glad this will be able to let me know if ... - I unsoldered SMPS Transformer and tested the Primary it matches what the tester confirms it will do I am glad this will be able to let me know if i have a Problem with the Primary of the switched Mode Power Supply. As for the Secondary, the red lights completely go off even on a working SMPS. Is that the way it should behave

## Questions & Answers

**Q: Will this test universal motor field windings? Happy**
A: It should be able to test motor windings. Best yet is to compare the readings against a known good motor winding. A complementary tester is the digital LCR meter.

Very good

### ⭐⭐⭐⭐⭐ Works great for go\no-go solution
*by H***Y on May 18, 2015*

Works great and arrived on time. I use this with my Oscilloscope to show how ringing is produced in a coil and cap tank circuit and is useful for testing coils for shorts.
