If you are concerned that the meter is mdamaged
and do not want a repeat spark event; try checking the meter against
itself in the ohms setting, or measuring a 1.5 battery, or a low
voltage AC source such as a no longer needed wall wart from an old
cell phone.

Wouldn't that be a DC voltage coming out of the cell phone wall wart?

I have seen a few AC wall warts, although most do seem to be DC.



If the wall receptacle had a metal plate on it, you might have also
accidentally shorted a lead against it.
I suppose that if you do not use a meter on a regular basis, you would
purchase the least expensive one you could find, and you consequently
would also have minimal experience making measurements; if you use a
meter on a regular basis, you know that having a good quality meter is
imperative for safety and accuracy, and you also have expertise in
taking measurements. If you cooked your meter, and did not stop your
heart, then you paid a small price for a valuable lesson in taking
measurments safely, and selecting higher quality when shopping for a
new meter.
hope this helps

the person has to READ the side of the transformer/wall wart to
determine if it is DC or AC.gee whiz.

the suggestion was intended to provide Sparky with a safe low voltage
source to use to test the meter, that's all.
Hey Sparky, are you still there?
