Thanks for sharing the idea behind the tests. Well, that's shane there is no ratting for multimeter robustness and no one the industry (i'd like to exclude you) has properly tested and rated the handheld multimeters for robustness. In fact it's quite surprising!
Anyhow your tests are pretty unique and I believe if you document all your tests methodology and their results, perhaps it could lead to a new trend and attract knowen manufacturers. I hope.
It sounds to much to ask, can we have all your test results in a single sheet including torture pulse duration and voltages? I found an Excel sheet, in the first post, but it looks just a bit outdated and not well documented. Also how the various multimeter failed, they just failed with no explosion or something nasty happened too?
If you watch my videos, the last meter I tested was the CEM DT-9939. This is the last meter entered into the spreadsheet, so it appears up to date. Looking at the header, the peak amplitude (voltage), source impedance and FWHH (I would guess what you are calling pulse duration) are shown for each level. The videos for each test are online so if someone wanted to dig into what was done, you can go so far as to watch it. There you would find that I subject each mode of the meter to five transients each both positive and negative (again right from the IEC standards). I already covered what my goal was so I am not sure why you would ever think a meter would explode during my testing. There is a link to a FAQ on my YT About page. That may provide some additional information.
I spoke with a few companies about their testing and wanted to know if they would make their data public and in all cases was told no and it is one reason I started running these tests and making them public. If you look at the reports that are available to the public, what information do you find? Not too long ago I linked one from TUV and that had a lot more detail than most!
If someone wanted to really run this test on a bigger scale, personally I would just follow the IEC surge test using all of the standard equipment. I would get that generator on the AC mains and I would build a nice blast room to go with it!
I would step the voltage in small increments and functional test the meter between each step as I do and document the results. Simple enough to do, but a huge investment. For a company, what would be the advantage to making this data public? Some companies like Fluke may be able to make a marketing spin with it but then they would also have to show their 87V as well. It's one thing for a hobbyist to say the 87V is not very robust, it would be a whole different game for Fluke to come out with data showing where it fits. I just don't see the companies ever doing this. Even if they did, I would be concerned the testing would be corrupt. Look at that
TUV Intertek report where they ESD test the meter without the test leads. The average person may not care but if bought a meter and knew this was how they got it to pass, I would not be happy. Really it seems it should be a not for profit, independent group running the tests as a watchdog public service. This would require some major cash flow.
I would like to see it on a large scale. Public education would need to be part of it. I really don't see how you would turn it into a business. The money needs to come from somewhere. Look at the comments in this thread and consider this is a tech sort of audience. I suspect the majority of people who would purchase a meter could care less about this sort of thing, so they are not going to fund it. You need to make enough to feed and house yourself along with your staff. Seems like a rough road.
Just blabbing... If you would like to make a go of it your self I would be interested in hearing about it.
