Easy access battery compartment.
The easiest assembly ever. All components are on the solder masked pc board.
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 = ??? or medium Q, green = Good or high Q.
