Dave i have a suggestion:

Get the remains of the meter laid out, glued to a backing and then put in a picture frame, and give it away as a prize ?  Be cool to have it on the wall!!

PS great video.   :-+

Amazing build quality of the meter  :-+
A drop test of 30 m would be more fun with a CRO  :-DD
You spelled CEO wrong ;)

@Max: Good idea.

By the way: Vandalism isnt funny.

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?

Some of the aerospace manufacturers of CRO displays have ones that, in the right mount, will survive that still working. Power it for the drop and they would not even jitter.......

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.

This will be vying with the Uni-T meter for the most-hated video.

Understandable why you would test, but driving over it went a touch too far IMO.

You've never done something to a bit of gear that wasn't in the manufacturer's testing playbook?

But dropping it 30m would have been fine?  ::)

That is the best Keysight promo video I have seen.
Well I know what my next handheld DMM will be.
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. :)

I didn't watch that part. Pretty cringe worthy video. If you were to drop a multimeter from 30m then the multimeter is the last of your worries to be fair...

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.

The Fluke 28-II that survived the test in much better condition than this one?

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. The Next handheld DMM will be my last, with the Beckman being my back-up meter.....

Always sad to see a fine piece of test equipment destroyed but it certainly shows they are built solid. Other then being a big large I want one now.

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...

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.
I think of it like the Mythbusters creedo. First you test it up until the claims. Then you try to reproduce the carnage by whatever means necessary!

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 :-//

Great vid, shows what you're paying for(or not). + Fun watching Dave smashing it up, who could've done it with so much passion :D Don't understand people not liking this, perfectly shows what the meter is made of, only missing footage of blowing it up with some high energy impulses. Big + to keysight for this.

I wonder why people think that video destroyed a expensive device. That multimeter is not expensive. Dave got it for free and it costs Keysight basically nothing too.

Dave, not your finest video by a long way.
Do you have a point?
I don't see the point either. Finally a test equipment related video with nice nature to watch (yeah call me sexist if you like -can't help it-).

Edit: that canyoning seems like a nice thing to do.
