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!

edit: typo get -> go

When the Americans wake up you might get complaints that he didn't shoot it.

It's almost guaranteed there will be a comment about that  ;D

Probably easiest to just send what's left of the meter to Taofledermaus.

But if he's busy, I'm sure I can assist.  8)

That's why there was Dave's pal on the ground level, with a walkie-talkie, I guess.

Remember to use the drive wheels of a car to run over stuff.  Might have been funny when Dave scuffed up the front of a multimeter, not so funny for this guy.

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.



The XP line is re-badged Hitachi Data Systems (HDS) with some help from HP on the firmware.

I do not understand why some people are complaining, you have to go to the end, you have to know how much torture it can stand. Dave, i would torture other one electrically, how long can it stand 20 amps, what happens if you try to measure 220V in ohms range etc...srsly gus, it is in the  name of sience.

Didn't get all this hate 6 years ago when I tested the fluke in the exact same way.

 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.

Dave, well I can only speak for myself, but I think people just didn't like to see a good instrument waisted like that, I myself was kinda hmmm what a pitty, but I understand that tests need to be made, so you know what's capable of, or if it's really as good as claimed, I watch Joesmith videos too and he stress test the meters to see how far they can go, and that's the same thing, so don't take peoples reaction too harshly :)  :-+

This is it in a nutshell...

Great vid, shows what you're paying for(or not).

You can't argue that ... and that's exactly the sort of thing Keysight would be hoping to see.  Why else would they give Dave a meter to destroy?

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.

Personal trainer, she will take you to the gym and in 2 days you will absolutely hate her guts. If you survive 2 months you will grudgingly like her and after 6 months you will thank her for the lifestyle change. You will also be a lot fitter as well, and capable of running a 40km marathon in some semblance of reasonable time as well.

I can't wait for the repair video! Sure the screen is destroyed but a new IR emitter/receiver and you can have remote communication with the unit.
