Martin, This video asks exactly the same question I posted to all the commentators (including you :) in my comment to your last video "Review: CEM DT-337 milliamp clamp meter." No one took it on (again, including you:), except for one other person who thought that I might be on to something. Anyway, I am glad that in the end you did reply by going further and making this insightful video. Ken
Thanks! I did not know that a device such as an AC Line Splitter existed!!! I will investigate further and perhaps get one for review. Thanks for bringing it to my attention.
Thanks for the mlliampclamp videos. I recently purchased the CM100 from your Amazon store and they have been very helpful in my understanding of its uses..
Great video Martin! You've shed some unique light on the finer points of using clamp meters. Have you seen AC Line Splitters such as the Extech 480172? They make easy and safe work of checking current draw on appliances, have 1x and 10x measuring positions, and don't cost very much. Of course they require a larger clamp opening than the CM100 and DT-337 meters that you've reviewed.
Hi Martin, By using the strong rare earth magnet you may have magnetized the two meters sensors. I would recommend that you have then "degaussed" otherwise they may interact differently from what you expected. Best!
After watching your video I decided to buy the CM100 and I have to admit it has been nothing but trouble. It is out by almost 10A in some cases. I have tried to contact the company to replace it and they don't want to know about it.
One way is to inch down the wire trying to push the two sides of the break together together (under power) you get them to touch and thus reveal the break. Another is to put audio on the open wire and slide a wire to a crystal earphone (or a amplifier input running wide open) along the wire to hear where the discontinuity (break) is. Or just assume the likely: that it broke near where the wire enters the box and cut it back a few inches and reattach. Getting the box open is the hard part.
LOL! Yes...I have mentioned the risk of rings and watches before.... Mmmm...I should have tried turning one meter over....will bear that in mind as a quick test.. Cheers.
I recently purchased a clamp meter and have noticed something. When you do your AC amp measurements your meter shows 0.0 and stays there until you measure something. My meter fluctuates and right now shows 3.3-3.4 not testing anything. Is this normal or a sign of malfunction? Thanks for your videos.
Hi Martin, with my clamp-meter (PeakTech 1635, 2A-DC-Range) I've experienced a remarkable and serious amount of deviation with respect to the N-S-E-W and the elevation position above horizon of the meter. To delta-out the meter and change the position of the meter afterwards wont work for me. Does it for you? I appreciate your work very well, keep going! Best regards from Hamburg, Martin
Hi There, Great tutorial, hope you can help we have an earth leakage in our home and I cant seem to get someone to find the problem. I have a clamp meter but not sure how to find this leakage. Can you maybe assist I would really appreciate that.
A step-and-repeat bench cover?!?. How Hollywood! Notice that the clamping mechanism is reversed for each of these meters (clamp button is on the opposite side). Would it have any effect if you turned one meter over? If you have 2 turns in the clamp, and include 1 turn of the return wire, it should read like 1 turn, right? Oh, and for safety's sake, always wear a metal watch band when working with electrical stuff. That way the coroner can read the exact time of your death. :-)
Hi, I have bet with friends that regular loudspeakers cannot have power near 2kwats going through it, I said that is impossible. Please, *can you measure that for me?* Just find real loudspeaker or better subwoofer with regular amplifier (ask your friends maybe) and measure it's voltage and current and then multiply, and better do it on osciloscope with dicient current clamp to see real waveform on current and on voltage. I haven't seen yet on youtube this kind of measurments, probably you'll be the first one.

Thanks Jim, I appreciate your support. Cheers, Martin.

My pleasure Ken.

Your videos are really clear and helpful thanks!

Very informative info. Thanks for sharing

Yup...I did check afterwards and it still seems ok after that "little" magnetic field!
If you where going to pick one to purchase which one do you think is better
Can u get a reading if u just put the clamp meter around the cable
LOL! Yes...I have mentioned the risk of rings and watches before....
Mmmm...I should have tried turning one meter over....will bear that in mind as a quick test..

General question: On a DC clamp meter, does shielding around the wire influence the measurement?
I recently purchased a clamp meter and have noticed something. When you do your AC amp measurements your meter shows 0.0 and stays there until you measure something. My meter fluctuates and right now shows 3.3-3.4 not testing anything. Is this normal or a sign of malfunction? Thanks for your videos.
complete explanation. thanks
i love that you have so many meters above you. :D
hi great video , can we use the clamp meter with a multimeter on DC volts and get the current reading?if not where can I buy one that I can, thank you
Everardo Camacho the clamp meter tells you current! You dont need a multimeter for current, just a clamp meter!
Hi Martin,

Is there a way to check where a break occurs in the cord of a power adapter for laptops, etc. so they can be repaired?
Hi There, Great tutorial, hope you can help we have an earth leakage in our home and I cant seem to get someone to find the problem. I have a clamp meter but not sure how to find this leakage. Can you maybe assist I would really appreciate that.
Very helpful, THX!
That was helpful. Thanks.
this very helpful thanks
does increasing the current stregthen the magnetic field?
bro i am gonna for buy Meco 1008 trms clamp multimeter. does it best ?
Thanks for the update.
Great video but it's not safe to use a metallic wrist watch when working with electricity. It is a conductor. Thanks.
King Amponsah I he lines it with kapton tape before he does every video. he doesn't have any arm hair under there anymore, though.
I always have a metal watch band and have never had a problem in my many decades of electrical work. You need to be sensible and aware.
It's dangerous only if you short 2 wires with it, if you accidentally touch live wire with it it's pretty much same as touching it directly with skin.
that Sinn divers looks great
Thank you!
