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

The input is routed directly to the switch.  None of them surge rated resistors, PTCs and MOVs to throw off your reading.  Put a little gasoline on the LCD lens and let me know what happens.  The free ones from HF have no trouble with this but so far every Aneng meter I have looked at was damaged by this.  Crack open the fuses.  Filled?   

Cliff Matthews:
Nice to see you back in the saddle Joe. After what you've been through, bloody hell is all I can say..

As for this new cheapo meter, it looks like volt/ohms goes through that 600ma fuse (on the PCB-bottom pic above). I'm sure there's plenty of room in this cheap case for a new video.. You could call it 20k or bust ha ha! (but did you buy a new camera?).

MacMeter:
This meters face plate is exactly the same as my $13.00 “Ragu 17B”, except mine does not have the temp feature, and my rubber boot cover is red. I would never need the amp setting, bought it to leave in road trailer, reading 1800 amp AC tractor generator. Just need to monitor volts and hertz. For $9, I’ll get this one as backup. I lost my 1st Ragu when I tried to make a 9v battery eliminator, and screwed something up, my bad, but at these prices they are practically disposable, and if stolen or broken, it won’t make you cry like losing a fluke.

Cliff Matthews:
Fluke's likely not excited on that model number, but then again, they may not know Ragu is a spaghetti sauce either..  :-DD

I've seen a few meters where they route more than the current through the fuse.   The problem I see with them is you may not be aware that you damaged the fuse and the meter reads zero volts.   You may not have a fuse on-hand and cram some wire in there instead, then go to use the current.  :-DD   

We talk with the insurance company today.  So far, I have no plans to file a claim as I suspect I can repair the big ticket items but I do want to make sure that if the lab were lost that it would be covered.   Interesting thing I did find out is that if the items were damaged by what they call a surge is they limit the electronics.  If it was damaged from lightning, there is no limit.  But in many cases a surge is caused by lightning.   :-//   

I do like the camera Dave shows.   I don't have a device in the house that will display 4K but the quality of the picture is impressive.
