Just a heads up. Like most people, I don't heed the warning to 'test on known live circuit first' or 'test leads first' when using my trusty yellow Ideal Vol-Con. THIS HAS ALL CHANGED. When doing a service call on a sign, I checked for live power (120V). Vol-Con gave the all clear, no power. I proceeded to disconnect the ballast and Zap..I got nailed. It turns out the Vol-Con lead had separated where the tester wire meets the probe and I had no idea.
I shudder to imagine what would have happened, if I proceeded to work on a "dead" 347/600V line.
Todays lesson, Don't be dumb. Test your meters before use! On the Vol-Con, just touching the two leads together gets the Continuity light going so you know the leads are good.
