If you make a 10 turn coil out of some, say 2.5 mm insulated wire and put 1 Amp through it, the clamp meter will read 10 Amps, 100 turn coil will show 100 Amps with 1 Amp in. I used to work for a NAMAS calibration laboratory in the mid 1990s and that's how we used to calibrate high current clamp meters. I have the Kaiweets smart multimeter that this meter is based on, and they are fantastic value for money. I highly recommend them, but I would take the safety rating with a pinch of salt unless someone has actually done a destructive test on one of these meters.
@@bambumbambu well he just expllained right there... by adding more turns. also if you got the uni-t ut210e that starts off with an even finer resolution. thing is like explained in this video (and similar videos on the uni-t meter by other people)... are other external sources of magnetic waves. which creates significant noise in the milliamps range. to make clamp meters less good option. you may instead do better with a wired ammetter or using some quality shunts
Actually it depends on where on the wire the clamp meter is being placed. The clamp meter is measuring the magnetic field strength and if you place it on the straight section of wire before the coil and some distance away from it, then the clamp meter will only pick up the magnetic field from the straight section of wire and give a correct reading. If you place the clamp meter on a turn of the coil then yes it will read inaccurately because the magnetic field strength inside the coil is related to the number of turns on that coil, as well as the current and some other factors.
@@zedcarr6128 I think you should have been able to deduce that from my post. I refrained from presenting the mathematical equation for the magnetic field strength of a solenoid as I didn't think you would understand it. It contains the value of the magnetic permeability of free space.
Dave would get an instant aneurysm from the total lack of safety features, but as long as you assume it's a cat I meter with coincidental cat II capabilities, it looks like a nice hobby tool.
Thanks - I just bought the same meter under a different name for some DIY HVAC work and it met all my needs. Really like the side bracket to hold a probe. The display can be difficult to see in bright sunlight, but that's my only complaint. Otherwise, it's just as good as a $300 meter for a home user like me.
We have similar clamp meter with same plastic case, black bag, and packaging box. It worked fine for our low voltage DIY automobile work. For high voltage work, maybe a different meter. . .

Do not leave the meter in the sun even for a short while, the display dies on these sort very soon, had a rebranded kaiweets HT208D and it doesn't even turn now after a month because of the display.
hmm, Ive got a small clamp meter exactly the same as your smaller one there 7:23 except mine is orang and black and its a Tenma. the low current DC range is super useful on the bench. The near complete lack of protection is a bit weird in these meters though, just one PTC there...hmm. the smaller ones have a bunch more, I think 5 or 6 PTCs and MOVs iirc but still no fuses at all, not even little glass ones. I understand that theyre primarily clamp meters, and the addition of probes and a few extra features on my Tenma and that smaller one are just extras really and not their main function, but with the inclusion of the full suite of DMM features on this model you'd think they might have added a little more protection, maybe even really going wild and blowing the budget on a fuse.
Wow a most exciting clamp meter. 🥳 All my new test equipment is with Bluetooth if it is available. Also, I use the "Infrared Thermometer Temperature" function on the Extech EX830 to check things like motor temperature and other things form a distance. I really like the GVDA GD166B for my wish list. 😎 Thanks for a great video.
Nice review and tear down. Yes, I have for sometime used the anticlockwise direction for screws into plastic to hear the click, which I did learn from you.
Probably okay as a budget option if you're just using it for bench repairs, the accuracy across the board was quite impressive. I'd take any CAT3 ratings it claims with a pinch of salt. The lack of separation or barriers between the female socket for the red test lead and spring connector for the battery compartment is a bit concerning, if the test lead is shoved in skew or if it breaks free at the solder joint on the board the socket may well push inside the tester causing contact. Also the red display wire already shows marks on the insulation where it was trapped in the spring. I wouldn't want to use this tester in distribution boards or panels where there could be high fault currents involved at main supply voltages.
Nice feature set, but I wish it had a mV resolution when doing clamp measurements under 2A. But I have another one just specially for that and this one has features the other does not have, both are low cost, so I will most likely get thus one.
Nice budget clamp meter, the input protection not very impressive though one 1 ptc and no MOVs but 600A range can be useful in certain situations. I think your clamp meter ut210e still the best clamp meter with 1mA resolution which is a rarity in clamp meters also it has better input protection with MOVs and ptcs
Pekná recenzia, už som jednu na takýto prístroj videl na kanále Drirr90, ja osobne by som asi kliešťový ampérmeter veľmi nevyužil, keďže robím jemnejšiu elektroniku a keď potrebujem merať prúdy, tak väčšinou tak do 1A, kde by už nemusela vyhovovať presnosť.
All right I've got an ideal for a multimeter is a display okay and then wireless leads completely wireless that would be the greatest thing ever Okay so I know that would be difficult to do but what if it just had a wire between the two and not to the display thing that would still be a significant improvement
Your accent is hard to understand for an American. Why don't you articulate? Ar-Tic-u-late? Put spaces between your syllables & words; hit your consonants hard, do not mush-mouth, do not run your words together? It seems hard to understand how it is that customer service agents hired by big corporations (cheap probably) from foreign nations (like India, etc.) will refuse to articulate their words, but keep on speaking fast, running mushy words together, wasting time, as the customer has to keep asking the agent to repeat.

Even more AMMMPPSSS!
And you know how to increase the conductivity to allow for more amps, right? Even more SAAAAAALT!

how do you measure small currents from 0,1 mA to 2Amps for example with a clamp meter? all these meters have a 20mA smallest current resolution

@@deang5622 If you have 10 turns of wire in a coil, and you measure the magnetic field in that coil, it will be 10 times bigger than 1 turn of wire.

I always enjoy your testing and tear-downs; leave it to your cat to challenge you to show everything. Best regards to you and your family.
It's a cool meter but meters should have a physical dial to pick the mode.
Continously pressing a button feels stupid
Without a dial is irritating IMHO.
Its just made for looks. And that display will be invisible in bright daylight.
@@Petertronic Futurism for the sake of Futurism is complete bullshit.
If it works, don't 'fix' it by making it worse

well yes indeed. but at least the clamp part is pretty safe, if you clamp it around properly insulated cables
But have you seen some of the things DiodeGoneWild has stuck in the mains socket?
Dave is a clown
That looks like a very comprehensive bit of kit, at a very attractive price. I'm very tempted to take a punt and order one.
the success is when after disassembly and assembly it works again ;-)

You are the best, but be careful from electric shocks

No way it's Cat III. The spring next to the red input jack is a funny business -- even if it doesn't fail direct the spark gap is too low.
Uni t meter is better?
But can the non contact voltage detector detect pillows?
Could you make a short video about that power supply that we can hear in some of your videos? The one that can supply 50 amps. At 9:42
Very good clamp-meter. Niiice ☺👍
Looks good and the price is good
Might buy it

I think your clamp meter ut210e still the best clamp meter with 1mA resolution which is a rarity in clamp meters also it has better input protection with MOVs and ptcs
UT204+ is also 600A. Similar to the one shown in the video, minus the OLED display, the auto-mode, and the function selector.
Hi. Is this the same as the kaiweets version smart digital multimeter model kc602??
Very useful video . Thank you very much
The red clamp meter blinked on you with the battery symbol at 10:20 , it seems it doesn't like NiMH rechargeables that much ...
No fuses?
Regular Amp meters that use wires and shunts need fuses. A clamp meter doesn't have a fuse since there is no meaningful current circulating inside.
Meters are still dropping in cost. I got the smaller Kaiweet and had to pay little more.
It seems to be exactly the same device sold as Kaiweets KC602 on Amazon. I'm confused. which one is legit
Is 208d better or this model?
No multimeter fuse...?
You should mod your old clamp meter to be 6000 counts.
Some guys made it to 9999 counts.
how can you do that?
@@hojnikb Maybe by changing the crystal oscillator
@@ЯСуперСтар That's pretty cool! Have to check my clamp meter if its capable of that too...
@@hojnikb Good luck. Did you find any guides? I think its worth it
Muj syn hlead tvoji Ceskou youtube stranku - kdepak ji najde? Diky za videa!

I thought there would be circuit diagram and code for the microcontroller as usual 😊
The interesting part is the input protection, or its actual absence. No single MOV.

How much the GD 116B
I bet version a is wireless 😂😂😂 there's a Bluetooth one I'd love to get but delivery is 20quid and take up to 60days to the UK 🤣🤣
Not much in the way of protection, just one little PTC. Should have a couple of big PTCs and MOVs as well and a big resistor.

Nice 👍
Again, its looks like a rebranded Habotest Clamp meter, HT205D.
Hope it won't blow up like the black UT-830B
I love your accent😊
Great
Not sure I like that setup, I thought it would be junk but ended up half decent lol!
Background white noise in video is very annoying to headphone listeners.
🐈❤️🙏🏻👍🏻👍🏻👍🏻👍🏻👍🏻
Looks like a Kaiweets rebrand. Good chance it is rubbish.
Not Kaiweets, but from Habotest. Habotest Instrument is the main OEM.
