Before spending hours rebuilding a hydraulic solenoid, test its coil. A shorted turn makes the solenoid weak or erratic. blue ring tester schematic diagram exclusive
Add a 3-position switch to select C2 values:
The Blue Ring Tester solves this by turning the component under test into a temporary parallel LC tank circuit. To truly appreciate this circuit, you must understand
Blue Ring Tester is a specialized diagnostic tool used to test the health of high-Q (low loss) inductive components, such as flyback transformers (LOPT), deflection yokes, and switch-mode power supply (SMPS) transformers. Anatek Instruments
What specific (flyback, SMPS transformer, crossover coil) are you trying to test? A shorted turn makes the solenoid weak or erratic
: When the pulse hits a healthy inductor, it creates a decaying AC waveform (ringing). The tester counts how many of these oscillations exceed a specific voltage threshold.
Once your Blue Ring Tester is calibrated and powered on, interpreting the LED readout is straightforward:
