6000 count DMM's (NOT a good $9 newbie meter..) Resolved.

Oh, interesting. Yours is the first time I've heard that they don't stay put.

Probably because it’s almost embarrassing to buy a fluke product that is so overwhelmingly BAD. :)

See Fungus, they even exist in the wild! :-DD :-DD

Yeah, one might think a ceramic tube would have some glass in them, but .....
Hope your lightning repairs are going well.

Everything is back together and running except for the Anker USB hub that was damaged. Nothing I could do except order a replacement.
I think its because the voltage rating is so low and they are not needing a safety fuse for an uncertified meter. I tried to get Fungus to have a look inside of that cheap meter he picked up but I don't think he ever did. At least with the free HF meters, you know there is no fuse on the high current and the worst possible fuse on the low current.
malagas_on_fire:
There are a lot of meters that have no fuse on the Amps range, for example the uni-t 50B. The mA range is fused and the voltage input, has a PTC, GDT, diodes, a fuse , hi-speed clamps.
Well for those use a fuse holder and proper fuse in series, say 10 Amps.
joeqsmith:
I plan to run this meter at some point. It showed up but I have not made any time to play with it yet. If indeed the fuse is used for all of the functions, I may just jump it to run the normal tests. Or maybe just give into the fact it will fail like any $10 meter and try to improve it. :-// I have not had it out of the bag but it does look very nice for $10.
