Blue Ring Tester Kit - Requires Assembly

This Blue Ring Rester kit 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. This kit will take 1-2 hours to build depending in experience. Full 1yr warrenty on parts.
