Nice job 5KY.
A couple of comments.
While I applaud all the testing you did, I did not expect any failures on mains up to 120V. I also would not expect any up to 240V. But, over 240V, I would expect some. I once had a Uni-Trend meter that did have PTC protection on the front end to handle Mains. But, when I looked it up, it was rated to 250V. If any of those meters have these 250V PTC's, they should all handle your testing, but may not be able to go to the 600V they are supposed to.
For the drop testing, I agree that it was supposed to be to wood, but that does not mean using your wood floors. All you would need is a piece of plywood that you lay on the concrete. I watched some Fluke videos where the wood was just laying on the floor, and you could see it bounce up when a meter hit it. I also saw some Klein videos where they are dropping to steel, and the steel is not a flat surface, which is about as tough as you can get to pass. But, they are using that to go beyond the standard. They even have a video that they drop a meter 40 feet from a bucket truck onto pavement.
I agree that losing the fuses at 3 feet seems bad. I would think all meters should be able to handle that. The B&K case breaking really surprised me. I expected better from them.
