I made a mistake while attempting to use a multimeter to measure the voltage on a wall outlet that I was about to hook up an appliance to. I set the multimeter to ACV, but I put the probes into the mains. There was a spark, the wires to the multimeter blew, but the multimeter is fine and the outlet still works. I just want to make sure that there isn't anything else I should be worriesd about, except for the fact that I made a bad mistake with something I obviously shouldn't have been messing with.
