I recently had an experience where I had loaned my meter to a technician, he left the probes in the mA position. I didnt check it like I should have and I touched the probes to a 575 VAC buss. B O O M ! ! ! Right in my hand ! After my heart restarted and I realized what I had done, I changed my underwear...
It's all just sparks it won't take your arm, it's probably Fluke trying to scare people into buying their testers... look up their continuity tester prices, it says all, so use your brains and decide, do you pay that price for quality Continuity tester or is it a rip off...
@@ambientblue-eyedmonkey8849 Someone in the factory i work at had this happen to them. Its not propaganda lol. Cheap 50$ multimeter literally got demolecularized testing what i think was 600V. Plastic powder was fused in the guy's face lol. Thankfully he had no serious injury.
@@ambientblue-eyedmonkey8849 "Just sparks" LOL. 3rd degree burns, blindness, deafness. Just sparks. Do you realize how many people have been killed by doing this? There are documentaries about it right here on TH-cam.

@Gizmologist09 They all have specially rated fuses inside anyway so yes I agree with you. (As I'm told): Our maintainance guy tried to meter the 480 feed to the building with a Fluke 87. The slight problem was he metered the 13.2 side of the pole pig and POW. The meter blew up in his face. I guess 13.2 can overcome any fuse or board foils and cause a big explosion. I think handheld meters aren't rated against that high of voltage maybe a few KV and that's it.
Fused at 2A or 20A many of the meters have that small fuse just to protect the meter. Most of those fuses are not high interrupting capacity and can't interrupt the fault. I think our fused leads are rated at 100,000 interrupting. You could have the smallest or largest fuse, if it doesn't have the right KIA it won't clear the fault this will happen.
Oh yes; I had over looked that point, They are ceramic filled for high interrupting currents, but I don't know the figures and would only protect for the lower voltages and currents. Thanks for reminding me, I should know better. :)
It is very common for someone to use a multimeter to measure 600V. This is a very common practice that electricians perform daily that could easily be prevented by using fuse leads. A simple user error like have your meter on the wrong setting or plugged in the wrong spot is all it takes. We have investigated many accidents like this.
This happened to me before but I got lucky I guess.. I was testing the ac voltage on a 500V outlet in my dorm because I was just testing around with a multimeter that I found, I switched from V ac to mA because I was just a dumb curious teenager and BOOM it exploded in my hand. Luckily it didnt blow up as bad as the one in the video but it was enough to scare the shit out of me.. Now Ive learned that dont switch to mA when working with high voltage outlets.
I think this was done at Kinectrics in Canada where all the arc flash testing is done. Pretty amazing. They have a better video camera now. Might redo this one!
Clearly you have never experienced an arc flash. This doesn't happen with low-voltages like the ones you specify (120, 240, 208, 277 or 480), but happens when thousands of volts are present with a very high available energy, i.e. thousands or tens of thousands of amperes of current. It can happen, it does happen. You just make the assumption it can't, because it's never happened to you.
Thankfully my meter is fused to 20 amps, and even fused to 2 amps on the lower current settings. That would indeed be a nasty accident waiting to happen otherwise.
And also when measuring current, we can't just measure across a wire; we would have to cut it or splice it in half so that we don't blow the fuse to our meter. :)

He is no longer constipated.
600 delta or 600/347 is a popular in Ontario Canada. The same thing can happen at 480 other other voltages.
That's why you want to buy a proper CAT IV 600V rated Fluke or Agilent.
The most expensive DMM won't cost you anything more than an accident.

That sound at the beginning scared the FUCK out of me.
25 kA... That's more than those bigger HRC fuses are rated in good multimeters! (they are usually 20 kA rated)
@TexasLonghornFan63 Yes it was a real fake dummy. We could not get anyone to hold the meter
This is the thing that i never do even I'm electricuted several times
@hannobisschoff1 good to know, I was testing for 10k VDC today on a turbine, that was assured to be cold. Very unsettling day lol

Ya we could not find anyone to hold the meter, a person could move a little but I think the explosion is so fast it would be hard to avoid.
ESA=Canada=600 volts instead of 480 volts.
Haha, it was one of our inspectors. Just kidding no inspectors were harmed in the making of this video
hes a mannequin
Thankfully my meter is fused to 20 amps, and even fused to 2 amps on the lower current settings. That would indeed be a nasty accident waiting to happen otherwise.
OK who would use a multimeter on that power level like that...
is the person in the video some kind of robot? he doesn't move like he is locked up and any one else would have moved i'm sure...
Allways used fused leads and you dont have to worry.
am I right in saying this?
Sorry, the sound is the sound
hope that was not a fluke 87
i guess id call it a day...

Dont test for resistance or continuity with volts selected. AHAHAHAHAH! Get a fluke!
