Blue Ring Tester Schematic Diagram Exclusive Jun 2026

This voltage is monitored by Pin 5 of the LM3914. The LM3914 compares this analog voltage against an internal reference voltage divider and lights up the 10-segment LED bar graph sequentially. Reading the Results

The blue light is faster to perceive in peripheral vision than green or red. You don't read numbers; you see the quality of a transformer in a single blip. blue ring tester schematic diagram exclusive

In a healthy coil, the energy rings down slowly over several cycles (high Q). If a short exists, it acts as a heavy load, absorbing the energy and causing the ringing to collapse immediately (low Q). Core Blocks of the Schematic Diagram This voltage is monitored by Pin 5 of the LM3914
