  • What Not To Do With Digital Multimeter

    Set to read current rather than Voltage. Power applied and KaBoom.

    Note: After it blows up, just close it. There's lots of wasted time in video.

    I wonder if they removed the fuse and hardwired it to get it to explode.

      Either that or it was a junker that didn't have any good fuses in it. My bet is they rigged it up some.

      Sometime I want to find and post pictures (stills) of a friend's old timer Simpson 260 VOM that really blew up when set to the wrong range. It blasted the case to bits. Being an old timer series 2 they didn't have any manor of overload protection at all in them back then. The new ones have multiple fuses and diodes to protect the movement. By the way the Simpson 260 KaBoom was something that was planned out and no one was hurt and there wasn't any building damage to note. I do wonder how many people did get a nasty KaBoom in the face when they goofed. Might be good I don't know how many.

        Here is a real stupid **** trying to have fun. I hope he learned not to try this again, but I doubt it and that he keeps on doing this stuff.

        Another digital multimeter gets blown up. This video is pretty good.

          I think they must have bypassed the fuse to make it go boom. Considering the current test setting is usually one click away from the voltage test setting it's very easy for someone to put it on the wrong setting either by accident or by an unknowledgable person. Huge liability issue so I'm sure there they are designed to protect against that. I've seen it blow once on a fluke multimeter overloaded in the current setting and all it did was a pop from the fuse blowing and a small spark which melted the tip of one of the leads.

          EDIT: http://www.youtube.com/watch?v=HaIsz...eature=related
          Here's another video posted by the same person and it specifies the leads are not fused as I suspected. This one REALLY lights the place up!

            The receptacle cover was already singed when the video was taken so it was not the first time, hence he obviously didn't learn to not try that again.

              I doubt that they had to rig that meter to make it explode. Multimeter fuses are expensive--the DMM-11A fuse used in several Fluke models runs around $8.00. You can buy a complete multimeter at Harbor Fright for $2.99. I don't think they can afford to put much, if any, protective circuitry in that meter for that price.

              There is an article about meter safety at:
