Quote101.4 Functional integrity
After the voltage of 4.4.2.101 has been applied to the METER, the METER shall continue to be
able to indicate the presence of HAZARDOUS LIVE voltages up to the maximum RATED voltage.
If this is relevant, then any meter you have failed before this video that also has a CATII rating or higher can't be sold in the EU legally. The ones that failed this video with a CATIII rating also cannot. It is my understanding, from watching a video by Martin Lorton at the Fluke facilities, that the US has no restrictions on the legal sale of multimeters, not yet.
There is another part that specifies that any meter should not fail in a way that could harm the user. I wonder how that is actually tested without putting a person in harm's way?

NOTE The METER is not required to maintain its normal accuracy. A maximum deviation of 10 % is acceptable.

Conformity is checked by inspection while applying the maximum RATED voltage of each

For measuring circuit TERMINALS RATED for MAINS CIRCUITS voltage measurements:
.....
14.101 Circuits or components used as TRANSIENT OVERVOLTAGE limiting devices in
measuring circuits used to measure MAINS
The test voltage is applied between each pair of TERMINALS, used to measure MAINS, where
voltage-limiting devices are present.
NOTE This test can be extremely hazardous. Explosion shields and other provisions can be used to protect
personnel performing the test.

That was pretty funny! Did you take the battery apart and find some small button batteries inside?
Your recommended Fluke 101 is holding up just fine so far.
My only real complaints with this meter is how slow the continuity test is and the lack of a back light for the LCD.
It's not a great meter for electronics work but it's a pretty good meter for an electrician, especially with the safety probes (which I don't think any of your other meters have).

Could you start by post a few pictures of what you are calling safety probes? I'll post a few of what was included with the meters. I suspect you have seen a different set of leads supplied with the 101 than what I received.
I am very interested to see how the UT139C behaves with your tests. I have been recommending it as a worthy meter for almost anything a hobbyist would need a meter for. It sure looks like it has proper input protection, so hopefully we will see!
I was not able to find the correct manual for it. Is the jumper on the left the 2 ohm and the right 12? So you add a jumper for the source?
I do not see where the power feeds into it from the manual or how if connects to the different circuits. They have a simple schematic and call out the values used. They do not show the AC at all. Is it basically just for the telcom industry?
Ones I am used to can impose the wave on the AC. L-L L-N L-G .... It then synchronizes with the AC wave. I think we can handle a 30A 4-wire circuit with ours and are limited to 300V for the mains. To test the meters you would need to have the signal ride on the AC. Imagine the fun!!
If it really is just the waveform, it still has the potential to do far more damage than my homemade generator.
You killed the Klein.
And here you go. Pictures of the Fluke 101, BK 2703C and the MASTECH probes. I fail to see why the Fluke 101 probes would be considered a safety probe.

Point is: Many cheap meters don't have decent probes.

So, based on this comment, it seems your work has a more powerful machine than what you built up. Any chance you can put the 3 survivors on that?
Now we are talking! 2 phase 16A model?
You get it all running, I am curious how fast it charges in 8KV. Ours takes about 20 seconds for 5KV.

Interesting that the UT90A only failed on the diode test. I figured that it would have fried the resistance measurenment as well.
Time to start thinking about what to do with so many non-functional meters.......
