Blue Ring Tester Schematic Diagram Exclusive Now

The device uses a sequence of eight tri-color LEDs to represent the number of oscillations (rings) detected when a test pulse is applied to a coil. This allows for a fast "go/no-go" diagnosis that a standard ohm meter cannot perform. Ring tester for Coils and Transformers.

The remaining inverters are paralleled (buffers) to provide enough current drive to the test coil/output probe. This ensures a sharp, high-energy pulse is delivered to the transformer under test. blue ring tester schematic diagram exclusive
