Blue Ring Tester

This tester was ordered in error, however it will come in handy to verify transformers and other instructors. It matches the ESR tester I bought at the same time.

I bought it as a kit. Assembly was straight forward and I modified the output section to give banana plug or terminal post fixings for the test leads, just as I did with the ESR meter.

Again I kept the blank end plate in case I modify the outputs to more streamlined flush fitting banana jacks at a later date.
