Great info. Did not realize that the positive and negative would cancel each other out when using a clamp meter. Thanks for making this video. NO such information in the instruction manual that came with the meter.

This video should be included in the manual with every meter.

Thanks for the video. It is surprising how many people did not think about this and reached a false conclusion about current by measuring the whole multi-conductor wire.

So glad I watched this first!! I was putting the whole cable (black, white, green) through the amp meter's clamp.I was about to return the device. Rechecked the wires and now they read what I expected. Thanks for the video!

After 12 years and still thank you for the video.

Thank you!!!. I thought my brand new clamp-on ammeter was broken! now I realize I need to make a little 3-wire extension cord with the 3 inner wires separated, so I can clamp on to the black or white wire.

I bought the full thumb hole 22 version in 2009. I was stunned with accuracy straight out the box. Your review is spot on. I went on to buy the bull pup then the 110 laminate which had a manufacturing fault but I sorted myself.All top quality German engineering. 👌

I feel like an idiot! I bought an ammeter and wondered why it didn't work when testing things in the garage :) God Bless you

Not exactly a "how to" tutorial, but it was exactly what I was looking for (show very low amps through an extension cord)

The hot wire, not the entire cord! No wonder I wasn't getting any reading. A good short and sweet video. Thank you.

Thank you. Clear and concise. Good information, well-presented, is timeless. Excellent.

Well that explains it. Bought one of these specifically to measure the amperage draw on my new pressure washer and I basically get just zero. In other words, I’d have to cut up my new pressure washer power cord to get an accurate amperage reading. Very frustrating. Thanks for the explanation.

Those glasses, that lab coat, that cross handed posture, take my money sir

Thanks for that explanation. I was on the verge of thinking my Fluke 325 was defective

GOOD VIDEO, THANKS FOR TAKING THE TIME TO SHOW A VERY GOOD WAY TO USE THE TOOL.

They aren't exactly intended for "home/casual" use, but rather industrial applications such as large systems/machinery/etc. I'm pretty sure he just stripped the extension cord as a demonstration tool, really. :-P However, I must admit that I'm putting together a very short cord, essentially just a plug and socket with the separated wires being accessible but of course still insulated, not too vulnerable to damage. Then I'll be able to test anything plugs into a socket. Not typical usage, no.

Bro no wonder. The canceling each other out had me in circles lol

Ahhh geez explains why my new Fluke meter isn’t working. Didn’t know it had to be only one wire.

Thank you sir for this 2 minute answer to all my questions!!!! Thank you so much!!!

Finally lol thank u for explaining I almost returned the fluke device

For DC, what you do is run it through the wire leads of the meter. The current then actually flows through the multimeter, giving you a reading. At least, that's what is typically done. I'm not sure if a magnetic field type ammeter such as this could be used to read DC amperage with different circuitry or not...

no wonder I couldn't get it to work. THANKS!

Even though this was uploaded in 2011, why does it look like 1985 editing?? I expected to buy a new Delorean at the end lol Thanks though, good info.

I feel like an idiot now... Thank you XD

cool video. I am just starting to learn about RV electrical systems. I am looking forward to more videos!

New knowledge for me. No wonder I could not get a reading. Now I know. Thanks

Just what I needed! Now I just need to make a jumper cable to use with it.

Thank you, Mike to show us it very easy to understand . now I know how to use it , very help full.

Now that I know to modify an extension cord, the server room's power distribution will be properly mapped. :-)

Thank you!! I was so confused

I have a cheap little clamp meter I got of the bay and today after years I tried it on dc and it appears to work, I have 2 battery chargers running in the garage and the clamp agrees with what the ammeters on the chargers are saying even shorted out the little one's leads and it read 16 amps till the internal breaker cut out, same as the dial on the charger. I always thought you couldn't measure dc with these units. It is a MT87 clamp meter.

Only if the clamp-on ammeter has a "AC" AND "DC" setting, or if it blatantly says "measures DC" on the package or "AC/DC" on the face of the ammeter. btw ac/dc is a good rock band too.

Exactly what I was looking for

Great video, thanks for the knowledge

Great video and great information right to the point love your channel

So it’s worth having an extension lead with the wires separated for when you need to test AC current.

what about the direction of the meter the current passes through + or - side on the meter, that does make a differnce

Thank you.

there should be a clampmeter that you can put around the whole cord and then since the negative cancels out the positive to show zero, there should be a button you press that j ust shows the negative or the positive. There must be a meter like that somewhere do you know of one?

Awesome! Thank you for this video.

So you cannot check an extension cord for amps, what else can you do? check the wire that is plugged into it? Not like I am going to cut into an extension cord.

I was about to get crazy!!! Thank you.

I clamped the jaws directly onto the insulated 3 core power cable supplying 220 volts to a bar heater that was pulling 800 watts and got a reading of 0.7 amps. Does that amp reading make any sense?

Thanks for the video, although the part at 1:10 about the white wire's current being "opposite" to the black is something I'll have to give some thought and study to. Having to clamp around one conductor certainly makes the process difficult if not impossible. Do people make, or buy if available, a short gadget with three wires separated, with a receptacle and plug, so they can plug in the device and test one wire?

Great tip!!

I measured amp on a conduit of our building, it shows 7amp which presents there is fault wiring. How to trace where is the fault wiring or maybe neutral wire goes to a different circuit? Is there any tool to find where the fault wiring occurs without tearing down the wall?

Can anyone explain how the white wire, which has equal current, is somehow "equal but opposite" causing the current to....dissipate!?

Any idea why a clamp amp meter would trip a CGFI outlet?

Problem then how can i test a two core cable? no use using clamp meter and my multi is showing continuity and 230v but cable is faulty

if we attached two wires of 12 voults does it double amps limit

Nice tutorial

he needs a closing catch phrase

can i attached red and yellow and orange wires of a computer pcu to take maximum amps

can I expect a $10 ammeter to work as well ? even on 5v usb 22 gauge lines?

thanks ❤

Your vid help, thanks. What is a good clamp on ac/DC meter for general use? Something under $50. Thanks again

Just excellent !!!

I love it

Very helpful

thank you for the info.

What's an "amper"? Is that like an ampere?

Thank you! I have for a long time planned to by one of theese meeters. Will it work the same way on DC current too?

Is this also true for non-contact voltage pens ?

Thank you!

Thanks, helpful.

Thanks for sharing

A grabby jaw lol. Technical name

Thank you very much. I measure is zero long time.

Thank you so much!!!

How accubrush paint edger work

Ampers?

does this work for DC current flow also?????

Thanks

Thanks sir

thank you for the info :):)

thanks a lot..

Thanx bro

How about 240V tho?? 🤔

why did the white wire not shiw current?, What is the purpose of it being there?

NO---SHOCK ZZONE!! NO---SHOCK ZZONE!!

good

Great,..just rig an extension cord like that one instead of cutting into the appliance power cable...my customers wouldn't like that.

I cant handle videos like this. ammeter? Would be for measuring AM radio stations? How about saying amPmeter Ampers? Amperes!

thxz

well something fucked it up..so yeah i removed it Lol...then yeah it was ok for awhile then yeah it just alll got bad lol.

Kurwa a myślał że nie działa.

Thank you.
