Damn we're geniuses! We just gave Dave the idea to do a "Top 10 Multimeters that suck!" youtube video series. Million views in a week guaranteed!
I think that the OP deliberately asks these kind of thought provoking questions and then quietly slips out the back end without really divulging if there was ever a serious reason for the question, I seem to remember a few other similar type of threads in his or her name
How about "Top 10 Digital Multimeters that suck and why". I've got a few picks already if you dare start this shit war!

Trolls just like to stir the pot and then sit back and watch it overflow. Look how far this one has come already!
I'm still amazed came back on reply 58 .......... seriously this has to stop ?
Honey, why did You wrote tons of shitposts here?
Keep in mind what analog dmm is a root way to understand metrology
and it did`t require expencive batteries
and etc
stop digitise world! stay ortodoxy!

Any Meter with the model number "830" All of these low priced meters are junk just waiting to blow up in your hand. (Submitted by Lightages)

That's why I wanted to change the title from "Top 10 Digital Multimeters that suck" to add "and why". For you, a list like this carries some weight. For me, not so much. The list is someone's feelings about if particular meters will pass these standards. There is very little data on how the meters would actually perform.

Maybe you missed the fact that most (if not all) meters listed have 250V glass fuses or unfused inputs when claiming CATII/IV ratings. That is hard data, regardless if it was subjected to testing. The list correlates specs and physical construction.

The real question IMO is could the meter contain the blast.

Blast containment is a whole other story, but certainly one of the main subjects of the EN 61010 and its subparts.
Based on their comment "The main criteria is that all inputs must be able to withstand the maximum CAT ratings in all modes of operation, connected incorrectly or not, without harming the user." this seems to be their primary concern.
Safety fuses are important when we talk about the operator having a stupid moment. But when we talk about line transients, which could pose the same threat, this is where his list falls apart...
with the meter leads in the unfused 20 Amp current inputs.
I'm asssuming some sort of BANG! ?
battery pop ?
'Unshielded MAW' tack welds ?
or smouldering spaghetti meter leads with tasty barbequed selector tracks and neighboring components ?

But when we talk about line transients, which could pose the same threat, this is where his list falls apart...I had 830 multimeter during my childhood. I once measured mains voltage with wire plugged in amps socket because I forgot to plug it back into volts socket. In result wire acted as a fuse, disconnecting itself from the probe near to solder joint (those were not molded around the wire and were hollow inside).
High Voltage and high bs CAT claims aside for a minute, what about if/when the average Richard Unfortunatto with a shiny new multimeter
sneaks out during the Xmas day hogout boozefest to measure Uncle Bob's crusty truck 24 and or 12 volt battery voltage,
with the meter leads in the unfused 20 Amp current inputs.

Might even take out some car electronics, including Uncle Bob's crusty CB perhaps?
Anyone seen or been there to confirm what the deal is ? LOL, I won't be anytime soon
I suppose my point is, you can't expect ANY meter manufacturer to bail you out of 'operator error' perhaps mashed with an unforeseen freaky one time (perhaps last time..) situation,
no matter what the claims and -controlled mayhem- Youtube demos
Maybe some meters will live up to a lot of claims, but what if you score a dud one
or someones sold off problem they messed with or unknowingly created
i.e. guys, if you're gonna do something risky/stupid/unknown
or one of those peeps that get off being a serial Darwin Award Nominee year in year out
At least get some long dry wood sticks or PVC props with tape, ties, glue, garter bands or whatever
with some serious personal PPE between you, and the 'CAT X?' meter and the possible source of DUT BANG!
and get some proper 'will blo' fuses somewhere in on the game too,
even expl0ding flying shrapnel glass fuses are better than nothing!
hey, and don't forget to switch on the freakin camera, and share on Youtube > PLEASE!
