It's guys like you who keep these manufacturers on their toes and hold them to a standard. 👍👍👍

would also like to thank you for taking the time to do these test. very interesting to see the failure points.

This is an interesting and memorable evaluation. It didn't require a thermal imaging camera to observe the results! A number of meters I have suggest maximum current test of 10 seconds in the instructions, but the CenTech is not one of them. I don't have this much equipment, but I think I could reasonably extrapolate the current carrying ability from milliohms using my 4-wire setup. Anytime I test a current above 1A I tend to remove the standard leads and use high gage banana wires directly to the jacks and keep the test duration short. If I must monitor the current for a long period of time, I will use my UT210E clamp meter same as what you showed, after zeroing out the earth's magnetic field DC offset in the correct orientation relative to the wire, which leads to extremely accurate results. Alternately, I would monitor the voltage across a high power low resistance shunt resistor in series to monitor current. Side note, in the current test some leads were left bundled with wire tie and some were unraveled. This could introduce a variable because of how well constant heat can escape the leads and where the break might happen. Non-tester wires are typically specified with an optimum insulator OD based on the conductor diameter and the thermal conductivity of the jacket. Low voltage wires with low isolation need are better at current carrying current because the jacket ends up being thinner. Tester leads capable of high voltage are not usually very good a high current because of this compromise. Then there is silicone which has higher combustion temperature versus PVC, which is a better conductor of heat. I would choose PVC for high current because you wouldn't approach ignition temperatures with appropriate use. It's more likely that silicone would fare better near a soldering iron on the bench. Silicone is mostly for flexibility.

I love the way that you sensible testing of equipment, always ultimately ends up with stuff exploding and/or bursting into flames :-)

I appreciate all the testing videos that you put online, thank-you.

great video joe they give an idea of which probes to buy and what not to buy but under normal testing they seem to me like they would all work well under normal testing

Appreciate the effort making this interesting video.

Also I think it would have been kind of cool to see you cut probes open and get an idea of the gauge & strand count.

great video, i hope you keep making quality content

Awesome testing bro

So, the CENTECH probes put out the most power and, therefore, are the best. Maybe the leads will provide enough resistance to prevent the breaker from tripping if it's inadvertently left in current mode when one checks line voltage. The leads can sort of act like an external PTC thermister. I decided I was done fooling with bottom of the barrel multimeters last time I forgot to change the probes from current to voltage inputs. I haven't forgotten swap inputs since I decided I'd only use meters with fused inputs. Who wants to pay for and go through the additional work of replacing a fuse, if you can just remember not to blow it? I've enjoyed your videos but I'm glad I don't have smellovision for the smoke in this one.

man I was hoping you were going to see how much the probe masters would suffer. Probe master is all I run and I love it. I wonder what the silicone leads would have done.

You can no longer sell that ASUS laptop as from a non-smoking shack. Great test!! Thanx.

"Remember kids, the only difference between Science and screwing around is writing it down."

Well, if the probe quality is any indicator of the products overall worth, it seems the Fluke is the winner. My guess is if a manufacturer wanted to skimp on cost they would short you on the probe quality. Nice video.

Pretty cool

Cool. The analytics software you present with is great too; did you write it yourself ?

Have to move my centech probes to my fusible link drawer

nice video. good test. witch probe would you say is good one for every day use at 5 amps all the to say about 15 amps maybe pushing 20 amps.

HOLY SMOKES 21:42!

That's why I only use 2.5mm^2 test leads rated for 32A, they can handle whatever the 4mm plug can handle. The probes that come with meters aren't all that practical anyway, compared to stackable banana plugs on both ends.

Nice, subscribed :)

Thanks for this extreme test. So in reality, Vichy VC99 probes; What they claimed was actually correct because they lasted 35amps before it failed. is that right?

Great stuff! Would have liked to see a 60 amp test of the ProbeMaster ones. Have the cheaper model and I like them a lot.

Did the probemaster fail before the last test? Or what was the reason for not testing probemaster to failure? Or have I missed when it failed?

👍👍

what is your profession on a daily basis?.. by the sounds and looks, I wouldn't be surprised if you are already retired. what are some of the projects you work on for your job?

finally fire and smoke !! lol

that high voltage probe looks like evil genius tech

I thought gold was actually a somewhat mediocre conductor, and that its use was just to prevent corrosion?

niiiice

13:18 - UNI-T UT61E is supposed to work up 10A.

Horrified that you would destroy all those probes with so much current! 😞

Polish the probe tips !

I've owned Brymen BM869s for 1 year. After a short time, a non-contact problem occurred with the test probes that came out of the box. It shows 2.2ohm resistance. I am not a beginner (25 years of experience) and have used the device very little. causing problems in a short time does not suit the Brymen brand. even cheap china probes last longer than that. The probes that come out of the box are old production. not silicone and no banana screw. I have now ordered a new one. They say these are silicone. the tip is banana screw. it will reach me soon. Note: I am using "google translate". I'm sorry I don't know your language.
