Hate it when that happens.

But it's the reason we were required to Live Dead Live in the factory where I worked, to be sure power was off before doing a repair.

Live (testing a powered circuit) proves your meter works.
Dead proves your locked out circuit is safe, provided your meter didn't die in between.
Live again proves your meter was okay.
