Title: EEVblog #868 - Keysight U1282A Multimeter Torture Test
Post by: EEVblog on April 09, 2016, 10:55:16 am
Dave & Friends destroy a Keysight U1282A Multimeter.
Is it really IP67 rated & can withstand a 3m drop?
Only one way to find out, take it canyoning, then drop it, throw it from a moving car, run over it, and then drop it some more until it breaks!

Somewhere in the debris will be the plastic base of the crystal. The through-hole and surface mount packages are identical, possibly even down to the leads, they just add a base and form the leads.

As for the piezo, the plastic gets really brittle when rapidly melted and cooled like that, so it's not really a huge surprise - don't forget the weight of the leads as well.

Somehow my heart really bleeds seeing perfectly working tech getting destoyed... just remember how we used to feel as teens - saving money to buy some basic equip ... and now there's that video with a guy just pointlessly destroying a new, working piece of gear for fun (with laughter) while you'd (in his place) really have loved to own, use that equip... and it isn't even made clear if that's a sponsored destruction so it would at least have the purpose of funding the channel.

Also it can't even be called a gain for science as the failure-modes were just briefly investigated (and non-repeatable).
For example: did the rangeswitch or the buttons leak water after the canyon? ... I must have missed that part.

IMHO that vid is none to be proud of.

 :'( :--

Maybe it's time for some real EE-stuff (like designing something useful) again?


PS/OT: I was even more disgusted by the TI "viral" video "will it BBQ" - buring a scope... why... just why... please show me something cool, not something any stupid kid with a matchbox could so. YT is aready overfilled with brain-dead content (ok, that's also attracting millions of watching zombies)... please help to keep a few corners zombie-free.

I seem to recall the meter being given to Dave for purposes of testing. Destructive testing.

How do you think they test whether they're waterproof and drop resistant? By pretending to smash them?

I was thinking a similar thing but more along the lines of a replacement LCD and then chuck it all in a box to create a Mongrel Meter for the bench, Dave would know best and whether it is salvageable or not or if it has already been recycled and is all too late, a redemption by resurrection would not only be a great project but may also make a very nice meter, I'd have a crack at this in a heartbeat given the opportunity.

I have noticed in some of the Youtube comments that people are displeased seeing equipment of this calibre destroyed and as somebody who regularly works at height I do see their point as we are compelled to tether tools and equipment more so if there is a risk to others, we also prefer to use the good meters at bench height and the shitty ones everywhere else so if they fall or grow legs then there is no great loss, perhaps it was meant to be more of a true comparison with what the Fluke had achieved and to do any less would have generated the associated negative comments, he can't win either way so even-stevens or nothing at all.

Dave, if SMD crystals are made the same way SMD electrolytic caps are made, then yes; it is a converted through hole part. I visited an SMD electrolytic capacitor factory and was amazed to find all the caps start as through hole parts. The leads are then stamped, bent and trimmed. Here's some pictures.

In the attached image you can see the leads of a through hole part being formed by a turret tool, which bends stamps and cuts the leads.

They crash test cars. I used to hate to see a brand new Lamborghini  destroyed. I don't necessarily agree that it is pointless. People interested in buying a rugged (claimed) multimeter like to see some actual trial results. As to sponsored, Dave funds the channel as a result of making content people want to watch. I wouldn't be encouraging him to take direct commercial sponsorship. That would lead people to wonder if he has a conflict of interest.
This are done under controlled, repeatable conditions to ensure the most possible protection.
The only thing Dave have shown is pure vandalism.
Spacial in the second half of the movie.

Its sad to see Dave is going the mainstream way of low quality content with this video.
But it hurts me more that movies like this gets the most clicks / views.

I miss videos with fundamental / informative ee-content.

Wonder if that PTC snapped off at the solder joint, or if the leads pulled out of the board entirely.

Actually a pretty good test of real life use, the water and the dropping off a sloped roof to land on ground, the abuse of being in a tool bag as is, the falling out of a vehicle at speed when you accidentally left it on the roof finishing off a job. Driving over because the guy behind was not going to swerve in time, and hopefully did not rear end you because you slammed on the brakes at the sudden "OHCRAP" moment.

The high altitude drop test, because one day you will be up a ladder, or at a window in a building and accidentally knock it out to do the long dance to destruction.It might survive below the 5th floor....... Anybody at Agilent want to do a drop test off a taller building onto a grass area and see if this holds up as well.

A through hole solder joint would be orders of magnitude stronger than a component lead.
The PTC simply sheared off under it's own weight.

Grass would absorb a lot of energy.
G force is directly related to the stopping distance vs time. Concrete = really really short stopping distance. Grass and dirt ground etc will have at least a few mm of give in it. So G forces will be several orders lower.

I do not think I have a single meter that would survive any of those tests and still be at any level or even capable of functioning after even part of that testing. Most, if not all, are not waterproof to the level of that Agilent, and I think most would disintegrate into pieces at the 3m drop testing stage. Impressive that it did survive the snubbed fall onto concrete at way above the 3m velocity, with only deformation of the PCB and case.  I think those high falls were what took the Caddock network off the soldered pins, and that network then snapped the PTC off the board, as it was directly below. Then the next series dinged the resistors as both went into the case area. Brass resonator popped off likely in the wall impact series, or on the 30m drop test ( did noone notice Dave reuse the footage of the first drop in the second where it went caseless?) when it hit face first, which would have provided enough G force to pull the resonator out of the plastic, the bending being evident. The leads were sheared off by the wall impacts, and the crystal probably went at the same time. Never saw the little plastic spacer they have under the crystal, probably fell out the case, and the crystal was crushed by the board flexing, either pre separation or likely afterwards in a corner of the case.

BTW Dave this was a good watch, especially at the amount of work you had to do to destroy this meter. Can you just do the drop test again using the regular 830 meter series, you might need a few to get past the 10m drop test part, and the car series they might pass ( one in a hundred that lands base first and skids along the tar) but I doubt they will pass the drive test, even if you use a Tata or a Hyundai A10 and drop tyre pressure to 1 bar ( basically flat tyre) for this.

Thanks for the video Dave. It's good to see independent verification of the waterproofing and drop test rating.
True Dave's video is partly entertainment but what's wrong with that?

Industry drop testing is done under controlled test conditions for repeatability. The disadvantage is that it can't test all possible scenarios and can miss real world failures.

I have enjoyed doing destructive testing as long as fixing the failures is someone elses job.

It's not "vandalism". Keysight specifically gave me the meter in order to have some fun destroying it.

It's pretty straightforward, I think.

Keysight gives one of their meters to a guy with a popular global presence and do some destructive tests.  This meter was always meant to be pushed past the limits and this was done - with some oddball techniques in places that were not a lab.  The fact that there was a bit of enjoyment and entertainment in the process is not a problem to me - I was more interested in seeing just how the various tortures affected the unit.

If seeing the destruction of this ONE meter upsets you - then I don't suggest you drop in on the Keysight testing laboratory.  You'll be crying for days.


Besides - who can not be interested to see how well a name brand meter fares under such extreme abuse?

I'm glad Dave does the testing so we don't have to. Yes I did need a minute to get over the damage on such a nice meter. Yet the thought that remains with me is "that is one tough meter." Reading the specs is one thing, seeing it in action is quite another. If I ever have a need for a tough meter like that, I'll take this one into consideration. It's a win-win for Dave and Keysight I guess.

That meter will hold up better than my Beckman (now Waveteck) RMS225, which I have had since 1991, and saw years of rough service in the commercial two way business. That meter still works quite well by the way...
But since the tilt stand finally broke three months ago it is time to replace the meter. :)

As far as the car running over test is concerned, I think the meter would have come out of it fairly well, if the first attempt went the same as the second.  It's the grinding along the road that did the greatest damage.  Like 2 grit abrasive with half a ton of pressure behind it.

I found the video, VERY educational. It also significantly increased my chances of buying Keysight multimeters (especially highly robust ones), in the future. But other makes, if similarly robust, would also be in my shopping list.

There are some circumstances where, you are doing electronics work, while working somewhat high up. Examples would be tall racks of electronics or servers, fire/burglar alarm systems. It could be for development, experimentation or service/repairs.
Basically any circumstances where you are using a multimeter, while on the higher steps of a ladder. The potential (please ignore the pun), to accidentally drop it, is always there.

So multimeters that are robust enough to take 3 metre falls on the chin, are of interest to some parties.

From a video point of view, would you rather see Dave, take a 3 metre ruler, and spend an hour dropping the multimeter(s), at different test heights. Which some would consider a bit boring, as the hour drags on ?

Or would you prefer to see Dave, spend the hour, in the exciting (to some), countryside of Australia, while simultaneously testing the multimeter at various drop heights ?

Once the multimeter, has checked out ok, at the specified 3 metres. It is then going to be interesting, to see how high it can go, and still survive, and also what gets damaged, when it does finally break.

It can at times, be difficult to justify to management, WHY you want/need to have (circa) $300 multimeters, rather than $50 ones. So videos illustrating how cheap multimeters, "EXPLODE", when accidentally exposed to very high voltages. Or damaged when accidentally dropped from significant heights, or from water exposure. Are useful additional means of demonstrating to managers WHY they need to budget for BETTER quality multimeters.
Obviously some managers would NEVER watch videos like that. Your mileage may vary. But if they do, at least it is available.

There's also a case for management not wanting to spend the budget on new kit without serious justification, such as being "bullet proof".  Videos like this can put the relevant extremes right in front of them.

There's nothing wrong with testing durability but at least put it in context. Dropping a meter from 30m (arbitrary) is not only careless but a health and safety serious concern of greater cost.
Driving over a meter is a hapless mistake.

Conversely, dropping a meter from a 1m workbench or up a set of steps and water ingress is a hazard of a workplace environment. Some of the testing was a tad overzealous like it's a video meant for Buzzfeed instead of the usual viewership.

Seriously?
I did testing of it's claims of IP67 and 3m drop. I took it further than that and it still worked. If I stopped after that then the amount of hate mail I would get for not seeing at wat point it breaks would have been an order of magnitude higher.

Possibly a more realistic test would have been to have plugged in some test leads and dropped the meter so that the plugs took the shock and transferred it straight to the sockets.
Many years ago I broke an Avo 8 Multimeter when it fell off a stool onto the floor while fault finding some industrial equipment. The meter had to be raised so that the test leads reached the circuit buried in the equipment.

So is my Beckman RMS-225, it has fallen off the roof of dump trucks, been kicked across the install bay floor (accidentally) gone down a flight of stares with the test leads installed. (that did crack the solder connection for the volts and ohms terminal.) And I cannot count the times it has been pushed off a bench on to a concrete floor.

Now I'm kinda curious how one of those $1 multimeters would hold up. The lack of components inside would speak in it's favor. Would the cheap, malleable plastic help or hinder? Although I guess the LCD would shatter instantly with no shock protection...

Those Eucalyptus forests are a banned item here though, which can only be planted in a controlled plantation for paper and pulp production, as they are both so invasive, water sucking and kill the local plantlife around them, especially when they burn.

The drop from the workbench and from the roof height did show how robust the meter is, all the fun in the water showed that is can handle water (But you need to clean the sockets afterwards), the rest was just fun.
My impression from the video is that the Keysight meter will survive just about any electrician (A electronic engineer would never get near any of the physical limits of the meter).

The fact so many people got their panties in a twist over an excellent stress test video is definitely worth extra points for trolling value. Sheesh, lighten up people. As they say, y'all must be real fun at parties.  |O

This video is being criticized, but this is exactly the type of testing you want to get the real truth about the durability of a product. This is on the same level as AvE doing a tool teardown. Dave gets to have fun, Keysight gets to sell meters, and the community gets a service done for them. It's a win all around.  :-+ :-+

If you've seen the BBC episodes of Top Gear featuring the Toyota Hilux destruction, they kept the car and mounted it in the studio.
They also had the 'Cool Wall' showing cars which were great or crap.

I wonder if you could do something similar; rate the meters by the drop they survived.

Also show products by how cool - or not - they are. Such as the ebay crud you seem to get often.
Viewer vote competitions on how cool or crud the products are?

Just some crazy ideas on a Saturday night.

Thanks for all the great videos Dave

Some managers would watch the video, and agree that we need new equipment, to give the capabilities of that multimeter.

So they would supply a £5 multimeter, and a £2 cord, to be fixed to the multimeter and the users belt. Failure to fix the belt, would result in the employee having to pay for the multimeter to be repaired. (Intended as a joke, but I know that in practice, there are too many elements of truth to this, in practice).

BTW I think a warning is in place. In the video you see the multimeter gets dropped close to a passage. If someone walks in there you can't see that person at the moment you let go but chances are you hit someone. Bottom line here: don't throw stuff from heights because you might hurt somebody seriously or even cause death!

Yesterday I was watching on a local news site a reader-submitted video of some kids throwing frogs at each other at the pondside. That's kind of retarded, I thought, but well, kids being kids, etc. A day later I watched a video of a grown man repeatedly smashing expensive piece of equipment against a concrete wall, woohooing with excitement each time :palm: It really was embarrassing to watch. Even if that was my idea of "fun" (it isn't), I would be too ashamed to admit that publicly :-//

I'd be too ashamed to admit publicly that I have no sense of fun, or the ability to comprehend the value of testing the robustness claims of a product.

Can you imagine the hate mail I'd get if I finished the video after the 3m drop? No, you probably can't...

I liked it.

I think it good to know just how well some things are built.  It is rated for a 3 meter drop fine, but does to get trashed with a 3.1 meter drop?

Sometimes it is not just the build quality but other things about the company.  I know of a product with a 3 year warranty, but if it ever breaks they will fix the thing for no more than the shipping.  Yes these companies still do exist and still hold a good percent of the market share because everyone knows the product is rock solid, and if anything does go wrong, they will stand behind it.

Back to breaking things....  And guns.

HP a few years ago had a video of one of their top of the line disk arrays taking a .308 round and still working.  Of course they made sure the round didn't hit all the boards/disks/busses in the array.

 Some people have nothing better to do than complain, about something, anything. And it also proves the selective memory theory. ONE other video like this EIGHT HUNDRED videos ago and "OMG Dave's gone mainstream" Despite the interesting history bits in the TTL video, a scope teardown, and some neat 2 minute teardowns in the mailbag video, all ALSO this same week - sheesh, what more do you people want? If the worse you have to suffer through is one boring (to you) video every 4 or 5 years, I don't see the point.

 I, for one, was amused by this, especially tossing it out the car window at speed. I was not expecting that. What does it all prove? Well, for one thing, the official specs are definitely not bullshit. Two, Agilent builds some pretty rugged gear. Three, the scenery in that canyon is gorgeous and I wish my knees could handle hiking, I'd love to visit that in person.

 You can do all the scientific, carefully controlled stress testing you want, but odds are a random fall out in the field will result in different stresses in different locations. So while the drop heights weren't measured to the nearest .01mm, it's still valid testing that helps validate the design and construction.

Yes, this would be an interesting addition to the drop testing. Hit it with the voltage and current limits after each test to see if internal circuitry was compromised.

I've had to test products to validate construction to whatever relevant standards there were. A lot of stuff gets wrecked, and the tests pay off when they lead to a better product. The extra margin in drop testing is what supports overall functionality and safety relative to the rated drop of 3 meters. If the meter shattered at 3.1 meters, then we couldn't trust it to be safe after a 3 meter drop. This has a 10x margin on height, which is something like a 100x margin on kinetic energy it needs to dissipate.

Dave, entertaining video for sure. I had a few chuckles.  ;D  Not so sure about what to think of the earlier comments on wasting a perfectly good multimeter. Certainly the world is no worse for wear and if Keysight chooses to give you stuff to destroy, it's their prerogative.

I've got the exact same request from Crest, who gave me 2 brand new electric toothbrushes... One of which is going to be a teardown and likely destroy the brush. I will eventually do a video on it and have no qualms about someone in the world who would otherwise benefit being unable to perform proper oral hygiene because of it.

In any case, I enjoyed the CANYONING footage actually more so than the multimeter. It was beautiful to see the natural scenery of the outback and some nice adventure hiking. I don't mind at all if the multimeter destruction was simply an excuse to get some canyon footage in there. It was fun and I only wish I could have been doing it!  :-+

Seeing all the hate here i must state my opinion on the matter as well. I don't agree with that hate here and agree that stuff needs to be tested/destroyed in order to see how well they last.
Only thing i got a bit annoyed was the lack of "documentation" of the experiment. It was nice to see Dave tear down and show us how the meter managed to resist water but why didn't he do it again when seeing the meter display shatter when dropping (losing the only obvious indication of life) I wanted to see how well everything else survived at the point where display finally failed.

Only difference between science and random vandalism is documentation.

What do you mean "in a few years"? It has been 6 years since EEVBlog #66 ("Death & Destruction of a Fluke Multimeter"). I guess the EEVBlog has been an "idiocracy" since then? If so, what does that make you?

There are plenty of videos showing how crappy products fail to live up to their specs. It's good to see one that shows a product that does live up to its claims.

And another thing, I really don't understand people who are somehow offended that Dave broke a multimeter, as if it were a holy relic or something. Come on, people, it's an assembly-line product, not a unique work of art. Crunch all you want, they'll make more.

Dave, just a thought...

When you threw it off the dam, why not let it free fall *without* the tether rope attached, and have your assistant at the bottom just hook it back on to the rope to let you tow it back to the top?

That way the multimeter could turn freely in falling and hit the ground at any angle, instead of only hitting bottom down as when the rope was attached. You could then throw down the rope to your assistant who would hook it on only for the lift back up to the top. When it gets back up, you could un-tether the rope and throw it down again.

The tether was used to initiate drops from intermediate heights - but I agree that the rope dragging over the railing would have slowed the fall.

To solve this you could hook the meter to a hold line and have a release line to pull a pin and let it free fall.

Alternatively, have the whole rope already hanging over the edge and just lower the meter to the desired start height and then let go.  Just use a rope 5m longer than the height of the platform and tie it off a couple of metres away from the drop point to keep the excess rope out of the fall path.  No rope dragging to slow anything down.  It's still not technically 'perfect', but it will be pretty darn close.

(most likely that resistor network but we may never know) I know you could not just go back to lab after each drop to tear it down and show us the results but either way that was the only thing bugging me.

You mean that same new low I reached 6 years ago when I did almost exactly the same video?
The same video that is quite famous and made a good part of my reputation?
The same video that the #1 requested thing people want to see when they visit the lab is the beat up Fluke 28?
The same video people often credit as one of their favourite episodes?
That new low point?

No, as I said, a new one, not the same one, it is lower and lower each year.
You argue that the video is famous and many people liked it... so what, does that make it a good video, if anything that only proves my point, the more stupid a video is, the more views it has.
I get it you make more money this way, but your reputation is going down, fast, when was the last time you did something of value.
I am pretty sure that you know exactly what I am talking about.


You're new here, right?
Nope, I am a long time fan, or hater ? (not sure, you decide)
I am silent most of the time, commenting mostly when somthing/someone pisses me off.
You don't have to get so defensive every time someone doesn't like your video, just take the good with the bad.



Yup, you're new here. Welcome.
Would you like me to create a safe space for you?

Nope I am not new here, but thanks.
No, I don't need a safe space (i am not sure what that is) you just focus your energy on making quality videos.
Thanks.

I think my post got understood in the wrong way.
(Sorry, my english isn't that good.)

I wanted to say that its sad to see a good multimeter ged destroyed.
But its Daves multimeter so he is free to do with it what he want.

The problem with this video is, that at least in the german language-area the most clicked-videos are te sort of "pranked bro", videos of vandalism,....
All together videos for people with low cerebral capacity and oversexed / desperate teenager.

I was concerned that Dave is slowly going the same way.
But this comments where because I like Daves channel very much and I dont want to see Dave drifting in the direction of high-quantity-low quality content.

But hey, thats only my opinion, a opinion of an old guy from the other site of the world, ranting at some clouds.

Demonstrably untrue.
My original Fluke 28 videos has 44,500 views in 6 years. One of my weaker performing videos in terms of long term views.

Of value to whom? You?
If you don't find value in my videos, that's fine, I only expect a small number of people to find value in my videos. But don't make out that you speak for anyone other than yourself, you don't.
Provide evidence that my "reputation is going down, fast".

I like feedback and ask for it regularly, and I spend a massive amount of time enaging with people on feedback even when I could easily ignore you.
What I don't like is people who think they speak for everyone, you don't.

If you said "Hey, I don't like this style of video etc" that's useful feedback. But when you say my reputation is falling blah, blah, and speaking like you know or speak for my audience, then you are just being silly.

No, I don't need a safe space (i am not sure what that is) you just focus your energy on making quality videos.

I make videos I like and want to make. If you don't like them there is an unsubscribe button.
I cannot please everyone, it literally is impossible.

Keysight gave me this meter specifically to destroy it. How many time do I have to point this out?

Yes, I know. I should have soldered a reference resistor inside or something, but I simply didn't think of that, I was too excited just to go canyoning and go dropping the thing.

Maybe try to keep that in mind in the year 2022 when you're testing another multimeter. More than once per 6 year period seems too much, considering all the hate here. Heck, probably Wun Hung Lo will start producing high end gear before "fans" let you break another test gear  :-DD

Some people actually like to give positive feedback and/or suggestions, rather than just stomp around when annoyed.

I liked the destruction videos very much!  :-+
Something different from the usual Mailbag Monday (although it is my favourite segment  ;) ).

Would be very interesting to see how a non-rugged multimeter (EEVblog BM235 for example) does in the same tests.
I would be interested to know how much more robust the 1282a or fluke 28 really are compared to a normal good quality meter.
Of course no canyoning if the meter isn't waterproof.

Keep it up Dave!  :-DMM

Was rather interesting to from the point of view of "at what point would Dave not be able to give it away". Pretty sure that was after he ran over it with the car.

As for the idea of doing it again with a cheap meter, we don't want Dave getting fined for littering, would take ages to pick up all the fragments of plastic and glass.
He Dave really wants to drop a cheap item from 30m, can we do that ebay crappy soldering iron ?
Though I suspect its out of the question, as Dave has likely poured wet concrete over it.

Formal drop tests are done at both extremes of the temperature operating range (-20c and +55c for the Keysight). Need to pack some dry ice and firewood for the next torture test.
Incidentally, ABS highest impact resistance and strength are obtained by molding at low temperature.

Great video Dave!
Nice to see a "non lab" test of a multimeter, you did this in a fun and nice way :)
(the only thing more fun is reading the "negative feedback" from some of the people here, they seem to need some kind of hobby to get some joy into their lives).
Keep up the good work, your videos have been of great inspiration to me (and many many others I'm sure) !

I usually like Dave's videos, I've learned a lot (and have also spent a good chunk of time screaming about how he gets stuff wrong or misses stuff on teardowns etc.) but it makes my heart ache to see equipment that I just cannot afford but would dearly love to have being destroyed, so, for that reason, no I won't watch the video.

If I was in need of a meter that could survive a dunk underwater, being dropped from a building or ladders then maybe I would watch it.

If Keysight sent Dave a meter to teardown and another to destroy then all power to their marketing department and Dave, this is after all about selling test gear and I much prefer Dave's 'warts and all' approach to someone who will kiss arse so they can lay hands on a nice piece of swag.

My point I suppose, if you don't like it don't watch it, plenty of other YT content out there to watch

I understand perfectly well why Keysight asked Dave to make this video. Fluke has become well known for their salespeople to throw their multimeters around in a lab or drop them out of a window without doing any damage to the multimeter. How do you 'me-too' something like that? Either way Keysight seems to be putting a lot of effort into marketing their gear to the lower end of the market.

What I like about Daves torture tests are that it's done to a meter that claims certain capability (IP67) - and it's not just another Youtube click-bait with something ridiculous like latest iPhone against thermite (something that it's clearly not designed to withstand.) And even as the test goes ridiculous at some point (driving over with a car, drop test from 25) those are the kind of tests that find the limits of the design - and the fact that meter is not in thousand pieces after all of that, shows that a lot of thought went into making this piece of equipment durable. Good video, thanks Dave!

Purposely throwing away or destroying perfectly useful things is still considered a major crime by many elderly Swabians. My grandma used to iron the wrappings of x-mas or birthday gifts she got. "Look, they are perfectly good, you can use them again!". No, I'm not kidding... Of course, with the younger throw-away-buy-new iphone generation this has changed a lot, but show Dave's vid to generation 50+ and it shure would get downvoted  :-DD

I suspect it's all the air inside the main body that makes it float so well with the orange rubbery clad.

The orange boot is for mechanical impact protection.  It plays no part in the IP67 rating.  Also, I cannot see it adding any significant buoyancy.  The bare meter will float just fine on its own.

Yep.

I'd guess it would - but in a random toss, it might be more likely to float face down.

I don't think much of all the criticism. Keysight sell the U1282A as being a heavy-duty waterproof DMM. We all know that marketing claims can be somewhat creative, so it's good to see those claims being tested. It's no different to checking out whether a meter meets its accuracy or safety specs. Yes, it's obviously informal and non-scientific, but what else could anyone do? It's also more demanding than tests in a controlled environment. I'd hope we all agree that this is a seriously rugged DMM that exceeds its specs. Ditto for the Fluke 28-II. No-one would want to destruction test their shiny new meter, so Dave has done the world a favour by breaking them for us.

As far as I can see, there are no losers. Keysight and Fluke have had their DMMs independently abused. Dave had fun making the videos, we had fun watching them. We can all see that both meters are hard to kill. And this information is in the public domain so everyone benefits for the foreseeable future.

I guess many people here will be lab-based, so this type of meter isn't that relevant to them. Perhaps that explains the negative responses. But DMMs are also needed outside or in industrial environments where all sorts of nasty things can and do happen.

I thought they sent him two of them, one to tear down and one to torture. Either way in his tear down he mentions there is no setup menu but there is. The rev 1 manual didn't even mention it which is why he had no idea it even existed. The newest rev of of the manual on the Keysight website is pretty decent if you want to review its features.
