There is tons of info online if you are interested in learning. Definitely something every electrician (who does any troubleshooting) should know.That makes sense but then I still have no education on how to actually do the testing.
We have oneThat Ultrasonic tester that (whomever) mentioned was something I had never seen suggested for electrical testing. Anyone else use one? I would think for the mentioned loose connection, the IR would be a whole lot quicker. Interesting idea regardless.
