Even more annoying is that I have damaged the
meter by my own stupidity
Measured the resistance of the mains?

You too, eh?
But they are indeed tough beasts; apart from a shaky ohms-adjust pot
it's still working 25 years later.

Doubtful if you could do that with a modern DVM and get away with it.

Not a cheap one maybe. My bench meter is a Keithley 2000 that will take
1KV peak when in resistance mode. Not that I'd do it on purpose, though...

A Fluke 80 series III or later can survive this - not sure about the
original 80 series.
I wouldn't do it intentionally just to prove a point, though...
