Ha! I thought you tied the multimeter to the back of the car and dragged
it down the freeway.

Stopped at 3:20min. Had to continue life.

Got interesting up around 10:00 or so... 30 meters eh?

Screw you Dave, I wanna see that thing under a sledge. Or maybe a log
splitter, or backhoe, or something...

Well, why bother, I have a 5 Euro multimeter,
if it blows I will get an other 5 Euro multimeter.
But it says it is 100% protected.
Why burn so many ? Just for the show???
Makes no sense to me.
He got it for nuffin just to test.

If you had seen some of his earlier videos, you'd know why. By all means use
your cheaper meter if you like, but there is such a thing as, "measurement
confidence". If your work is important, perhaps with lots of money or even
someone's life potentially at stake, which meter would I rather rely on? I
think the answer is pretty obvious.
I own meters large and small, el cheapos and better ones. But when I really
need to know, right now and with no bullshit, I reach for the Fluke.

Nice field trip. Most impressive !
I did think that the LCD would have broken much sooner though.
The inductor failure could have been prevented.
Good one.

I bought an expensive Fluke multimeter 20 years. It continues to work well,
and has only needed to have the LCD contacts cleaned (twice). I'm almost 63,
and if I live to be 90, I expect it to continue to work.

Harbor Freight sometimes sells their cheap multimeter for $2 (!!!). I gave one to a friend for Christmas, because he needed one for occasional work. I can see taking such a meter into places it might be damaged or destroyed. But I wouldn't use it for daily work. E E Jan 1, 1970 0 David L. Jones said: The title says it all really.

Better to stay away from mains with those.
I learned that hard way when I measured a water heater with some unknown
cheap meter.
First measured phase-to-ground 230 V fine... then phase to phase BANG
Fortunately only 16 A fuses on that circuit, so only damage was charred
multimeter. Think
if someone were dumb enough to measure something protected with 250 A
fuses... Like
if he forgot his own meter in car and sees nice looking meter lying
somewhere and actually
believes the "CAT III 600V" text printed on it. "Well, this meter should do
the job" and then
it shorts in his hands at about 1/10 voltage CAT III meter should withstand.

My AUD$3K Fluke PM97 failed from normal use. The batteries wouldn't hold a charge from day 1, the AC adapter failed after only a short time, one of the probes failed soon after, and then the meter itself failed. The service manual was missing the power supply page (maybe some Fluke/Philips tech used it and forgot to replace it). One day I'll step on it ... again, and again, and again. - Franc Zabkar W William Sommerwerck Jan 1, 1970 0 My AUD$3K Fluke PM97 failed from normal use. The batteries

Then why wasn't it repaired/replaced under warranty?

Well, Fluke Australia had given it to him to review, and they said he could
torture test it. The new models 27 and 28 replace the previous models
renowned for their ruggedness, so I think it makes sense.

The 100 foot drop onto concrete left my jaw hanging wide open. Then he did
it AGAIN without the rubber holster...oh, my.

Want to bet they put a little RTV on those inductors in the future?

Precisely.
The unit isn't just sold as regular multimeter, it is specifically designed
and marketed as a super rugged meter that is designed to survive abuse and
water ingress, just like the original Fluke 25 and 27. If that wasn't the
case you'd just buy the identical model 87V.
So to NOT test those aspects would be a poor review indeed. And then to only
drop it from 3m where I know it's going survive is kinda pointless. So it
makes sense to push it and get a meaningful data point at which it does
actually break.

My jaw was equally wide open!

Amazing. I doubted the 3M drop spec. Not any more.

I bought it in Australia, but I took it to Singapore. I suppose I
could have made the effort to have the batteries replaced, but I
relied on the AC adapter, until it failed.

More tests beyond specification:

Drive over it with a car.
Drive over it with a heavy truck.
Have good athletes kick it into a concrete wall.
Put it into a cement mixer running for 10 minutes (first dry then with water and finally with concrete).

Electronic BDSM. There is a small sub-culture of individuals in the
electronics business that is dedicated to torturing test equipment. I
don't pretend to understand the motivation, but there is ample
evidence of it on the authors blog:
<http://www.eevblog.com>
under the thinly disguised cover of "testing". The practice is
apparently widespread, as shown by the condition of used test
equipment found at flea markets and surplus sales.

Unfortunately, electronic BDSM sites are flourishing on the internet.
Many technicians and test equipment users apparently find some
perverse pleasure at watching their daily tools flogged into eWaste.
This must end as the next generation will certainly presume that such
abuse is the normal method of operation. We learn by example and such
sites are certainly a bad example of proper behavior.

While it is socially unacceptable to inflict pain on humans, there is
no such stricture to not do the same to test equipment. I suspect
that the Humane Society will eventually expand its scope to include
test equipment and other devices that are unable to protect themselves
from abuse. Meanwhile, the best I can suggest, to avoid repetition
and possible expansion, is to demand that test equipment be produced
and tested in a non-violent manner.

Well, how do you get around using a reflow oven or some other soldering?
