Now that I have benchtop DMM's, what I find annoying about my handheld DMMs, is whether or not to leave the batteries in them. I don't use them much anymore, and I use rechargeable batteries. I don't like removing the rubber case, or messing with the screws, too easy to strip them or the holes. I would like a DMM with battery pack that was spring loaded, and you push it in til it locks, then push again to release and pop back out. Not that practical for some users, but that's what I want. |

There is a shock hazard with a multimeter if you can touch the batteries, SD card etc. anything with a path leading to the input jacks. Safety codes require use of a tool for access or cute isolation method. |

That's not zero ;D The problem here is battery self discharge. Can't leave them in the drawer and expect them to be just fine indefinitely. Not to mention chemical leakage etc. |

I'll post pics later if you like. |
