        I know I am. Lucky because that 315mA 250V fuse blew before any more damage was done. If that fuse hadn't blown, I wouldn't have this mulimeter back up again.

          i avoid this by blocking the current jack on my meters and only testing current with a clampmeter.

            STJ speaks wise words. lol

            Also, I know that this situation is a bit different since you were testing the socket, but if you work commonly with mains stuff I would suggest making a light bulb current limited supply. For the cost of an extension cord, a ceramic light socket and a tungsten/halogen bulb, you can have a socket that will light the bulb up when you make a short while also protecting your equipment/device under test..

              Ah... it's a shame a board that spacious doesn't have A) a 10a fuse and B) HRC fuses...

              Ironically, that little gap where the trace was would probably fit one of those tiny 10a hrc axial lead fuses and give your meter an upgrade. Lol (Just heat shrink it well to keep it from the shunt/other terminals.

                or put an inline fuseholder on the probes wire - fluke sell a probe like that!
