Every inductor has a quality factor (Q). When you strike a good inductor with a short current pulse, it rings—producing a decaying sine wave. The number of cycles before the signal decays to 37% of its initial amplitude is proportional to the Q factor. blue ring tester schematic diagram exclusive
: It is highly effective for finding single shorted turns that a standard multimeter's continuity test would miss. However, it may not detect high-voltage insulation breakdowns that only occur under actual operating power. Procurement and Resources : Community-driven guides for building your own version
: Low Q (Quality Factor), typically indicating a bad or shorted winding. Yellow LEDs : Marginal or medium Q. Green LEDs : High Q, indicating a good component. Key Components & Resources The number of cycles before the signal decays
Building the circuit is one thing; calibrating it is another. Here are three exclusive calibration tips for this schematic:
