18:18 nah, the viewers have barely noticed 18 minutes have gone by, the viewers love the long vids with lots of drawings and tests :)
True!
I actually fell asleep twice when trying to watch it, but it has nothing to do with the content. The cause was my lack of sleep combined with the relaxing voice of Danyk.
@@atdzsny lol I did the same a couple times when that afternoon sleepyness hits after I had 3-4 hours of sleep
YEP !
Yes, these videos can't possibly be too long. Even if I needed to watch it in parts every day for the whole week to finish it. I subscribe only to few quality channels, and there are plenty of times without any new content at all...
I'm glad it belongs to secondary pollution.
I had one that belonged to primary pollution, it was really quite horrid.
Love the longer videos and especially love your cat!
I bought the multimeter following your link, hope that they reward you for this, thank you!
Bought this to replace my trash meter, so I'm happy to see you made this video while I'm waiting for it to arrive
But this meter isn't much better.
@@simontay4851 i think it will be a strong improvement over my "travelmeter" that can't measure voltage anymore.
this would be great to have in a car, small bright, big display numbers, and probes that can fit into all sorts of car oem plugs. Good vid man, thanks. When you gunna hit up Lidl again?
Propably when Lidl has any interesting stuff
Yeah, more Lidl/Aldi stuff would be great!
Car battery chargers, car battery analyzers would be nice.
The stuff I've seen in Lidl recently tends to be the same as it's been for the past five years or so. I almost bought a USB PD power supply there a couple of weeks ago, I guess a teardown of one of them could be interesting. Generally Lidl/Aldi stuff is well made, they have to conform to EU safety standards and everything has a 3 year warranty.
I think the accent is very delightful he sounds like he's singing I did not know Czech Republic had such great singers...
Very delightful!
Je to šikovný prístroj, pre bežné merania, kde nie je treba extrémna presnosť podľa mňa plne vyhovie, vďaka za video.
That 18 minutes flew by! I would watch if they were 18 hours long :D Nice review and look inside. Very interesting :D I did not know your power outlets were the reverse of the UK, I am going to have to do some serious plug swapping when I retire to the Czech Republic! Thank you :)
Well that's a cool feature. the live wire detection. That's great for determining if an outlet is wired properly whereas a three light tester can sometimes read false positives if the hot is incorrect. This can also be done with a noncontact tester but sometimes they are a little false positive due to sensitivity.
Nice review. Greetings from Poland!
I like the longer videos
Well done, sir.
I like the palm-size unit, the large display, the auto mode (I'm very lazy), the sharp test leads (for breadboards) and the fact that the test leads plug into the bottom of the meter, not the front. The lack of current measurement would be a deal breaker for me though, plus it's not cheap compared to competitors. The inaccuracy in temperature measurement is a bit of a worry too.
lack of physical bottons also is a big no
@@ingulari3977 It looks nice, I would love to see an internal review on that too.
You think 27 euros is not cheap ?
I'll never understand why these companies don't spend like an extra 5 minutes to proofread the English parts of their packaging/instructions. Worst case... they have to pay someone to check the copy for proper localization. Even if the product is great, seeing bad English, which they're literally using to SELL the product always makes me nervous.
That said, it looks pretty cool!
It's literally free using internet checkers, AI.
Well, the instructions are still good compared to the product I'm going to show tomorrow :D
@@DiodeGoneWild I finally have the income again to join your Patreon. I got to see that video, and WOW! It's truly incredible! hahaha!
The Chinglish is fun though, these review videos would be about half as long and half as amusing without it.
@@igotes THAT.... is a very, very good point! 😄
Damn what a generous company, look how many things they've sent you free of charge haha
What a nice meter.
I Am From Pakistan Your Video's are very Motivate me To Find Real One Thing's😍🥰❤️
Well done my Friend🙂🤝🍀
That USB connector looks quite touchable. I'd stay well away from that whilst using the "CATIII 1000V" functionality...
Anyone working with HV will have a Fluke meter, surely. As a hobbyist working with low voltages my UNI-T meters have served me well.
When I was a child I asked an electronic engineer friend of my dad why he had such an expensive multimeter, when my £5 one did everything his did (at least as far as I was concerned). His answer was "If you turn up on site with one of those, everyone will laugh at you". I get it now. if it's a tool of your trade you want to be sure it'll be accurate every time, and won't kill you.
Absolutely. In no way can this product meet the CATIII 1000V standard, it seems CATI 600V max. to me.
In general terms these cheap DMMs are just that: cheap. For their intended purpose they are commonly not useful and often dangerous, because safety standards are often "nice to have" for them.
20A cables and no current mode? Hey Kaweisi is 5x cheaper! But white LED test wow! AND: Your cat is much prettier than any of the 3 Louis Rossmann cats!!
I wish I could justify buying this one so I guess I am stuck with my $7 beast. The size of the display would be justification in a couple of years if my eyes keep deteriorating they way they are. 🤓
You have a *very* sarcastic cat which only goes to prove that it's actually a real one so that make the cat....... *Very Niiiiice!!* 👍
*Thank You* for the video. 😀
The sharp probes are nice. Mine are very fat with insulation around them. They could have fit more buttons for direct access to modes.
the thing it can auto measure random things is nice feature to have :)
So nice
DTM0660 again ? I am impressed by this chip. It's in manual range, auto, clamp and even smart meters.
FNiRSi read as faynires，it's a small shop sold simple and opensource electronic items for few years，nowadays it turns into a more active “inventor” for small appliances
Plug it into your PC to charge, and while it's connected try to measure the AC mains voltage.
I dare you.
No, don't actually do that, you would be staking danger and destruction on a coin flip.
Instead, let's just marvel at the hefty insulation on the probe connections, in contrast with the easily touchable USB port (especially with a charge lead plugged in!) and the probable lack of isolating device between the two. (Is that what the relay does? Nope, I can see at least the "COM" tracks go right on past it!)
Yes, the black probe has no separation from the USB port... I didn't think about this until somebody mentioned this problem in the comments.
for low voltages: okay. But for higher voltages like probing live circuits or industrial panels: Nope.
The meter has almost no input protection. Also i do not like the fact that you could measure 1000Volts while having a USB port exposed, or worse: connected to something.
Would be interesting to test how good the separation between the USB and input jacks is and how the meter behaves if "misused" (measuring 1000Volts on resistance mode e.g.)
Well, the separation between the USB port and the black probe is ... non existent.
I come here for the electronics, but sometimes I just like listening to his voice.
Maybe it's impolite, but his voice do add some fun to me. No offence, Diode.
Top very good.
I remember when I bought my first DMM. It was a Fluke 77, and it cost $320 Canadian back in 1989. I took good care of it, and it still looks and works like brand new. I have bought a few Fluke multimeters since then and have not had any problems with them. The thing I am wondering about is how long these Chinese meters will last. Given the track record of products made in China, I am a little skeptical about that. I have also noticed that some electronic products made in China in the 90s had better quality components in them than what they are putting out now.
Chinese manufacturers were using components imported mostly from Japan back in the 90s , we didn't have strong electronic industry at that time.
In general terms these cheap DMMs are just that: cheap. For their intended purpose they are commonly not useful and often dangerous, because safety standards are often "nice to have" for them.
@@TheBalconyWorkspace That makes sense about the components made in Japan. I opened up a single outlet surge protector made in China from 1996 for Radio Shack, and it has good quality MOVs and safety capacitors. The quality and design of the circuit board are well done. It seems like cutting costs within the last 10 or 15 years is the priority for many manufacturers. There are still some products from China that are well-made if you are willing to pay more money for them.
9:10 is it possible that the default thermocouple setting does not match the ones they gave you? Can you switch thermocouple type somehow in the meter or does it only support one type? (probably K)
Thanks
thank you for your support ;)
Multimeter tip covers seem like such a good idea but they are almost useless without some kind of tether to keep them attached to the probe. Otherwise you will just lose them.
The meter overall is nice the only down side is the build in lithium battery which have to charge it often.. I prefer AAA or AA battery which if i dont use for long time i can remove the battery . there is some auto DMM with removable battery also some they able to speak the reading ..
Impressive.. Chinese stuffs are getting very good.. also seems quite competitive.
Of course, It won't be enough to use in the field, but who would use this in the field lol
The inside is blatantly a UNI-T unit. The placement of the symbols, the digits and font, even the beeper is the same lol. But that is a good thing because UNI-T makes decently good stuff.
Nice.......
I would do some ESD tests
Is there a connection between the USB charging port and the probe connectors? If they are connected it would be quite dangerous with live mains being exposed up on the top of the meter....
It appears that they "share some common ground" haha.
That thing's potentially quite a hazard. Imagine if someone left a charging cable plugged into it.
Yes, no separation between the USB port and the black probe...
@@DiodeGoneWild OUCH!
@@DiodeGoneWild They should have used a special adaptor that re-uses the probe sockets for charging. I mean some connectors deep inside the bottom of the probe sockets, isolated from the probe connections, and an USB-C adaptor that plugs into the probe sockets, reaching the secondary connectors in their bottom. This would be the only feasible safe way to charge it, because it would prevent charging while the probes are connected. The other option would be a DC/DC converter, but a DC/DC converter that is OK for 1000V cat III isolation would make it a lot more expensive.
pretty sure you don't charge it when using the thing
Put it in resistor mode and try to measure 400VAC.
If it still works after that, then i'll be surprised.
Its probably good for quick measurements and low voltage DC stuff, but when doing electrical work or fixing something like an SMPS I usually reach for one of my Fluke or other name-brand meters. If they were honest and dispensed with the "CATIII 1000V" rating then it would be an ok meter for the average DIYer since it wouldn't be making claims to things it can't do.
Nice pocket meter, simple as it gets, but the LiPo battery? C'mon... I'm allergic to non-user-replaceable batteries. It'd be way better if it was tacked to the bottom shell of the enclosure, but attaching it to the PCB is asking for problems. Well, hope that WD40 and a spudger would do the job if needed...
Cat: winks
Me: winks back at the cat
Eu vi o vídeo anterior onde você estava usando este multímetro digital, eu achei muito interessante, eu pesquisei sobre o multímetro e eu não sabia que é chinês, eu não sabia que você gosta de multímetros chinês. Mas será que vale a pena um multímetro chinês?
Nice review... but why is this not in the dodgy category? the safety seems scary! would definitely not use it for mains ;)
Pekna recenzia... ale bezpecnost tej masinky ma trochu desi ;) rozhodne by som nepouzival na sietove napatie
I would be curious to know if the USB output would allow you to run an app on your PC and output the values there..?
I think the usb is just for charging. And also, the USB is not isolated from the probes. Using it and connecting it to the PC at the same time wouldn't be safe.
@@DiodeGoneWild Thanks for answering... Got it...
Try the Display under sunlight outdoors. Totally useless there.
Of course, under direct sun, only the traditional (non-inverted) LCD makes sense.
TH-cam should require every video to include at least one kitty.
please !!!! can you make a ZEEWEII DSO2512G oscilloscope review???
I'd rather have a physical switch (rotary or slide) instead of pressing a button multiple times and having to check that you're in the right mode.
"It belongs to secondary pollution"
I wonder who this Secondary Pollution guy is, he might be missing his multimeter 😅
They probably meant it can be used in environments of "pollution degree 2" . Chinglish at its best.
Half the display is wasted unless one is interested in say mains frequency.
Question is though: How long might it last?
The Aliexpress link in the description doesn’t work.
But I checked: €26 / £18.
Seems you get ripped off if you buy in Euros.
Man why would they cheap out with current mode, it would be a nice Allrounder otherwise
I miss when you were blowing stuff up...
No current measurements ? Nobody measures current anymore ?
Of course, this is not useful as your only multimeter. But if you have more multimeters like me, it's still handy.
In comparison to UT-210E (it has clamp meter) I find it "poor"
The video is not too long for me, but maybe you make more short videos and split it into parts. Short vids = more views = more earnings.☺
Hm can anyone explain me how can it measure frequencies over 4MHz if the crystal is only a 4MHz one? Is it using a frequency to voltage oscillator?
Possibly a PLL inside the MCU.
frequency multiplier
@@omniyambot9876 uh or maybe divider
@@fabriziobrutti1205 yeah was also going to say. Multiplier for source oscillator or divider for input oscillation...
@@omniyambot9876 agree... We just have to wait for Diode to answer :)
18:13 No, I am definitely not. But I should at this time :D
Please review more products from this company
More are coming ;) I also have some signal generator and soldering iron from them.
@@DiodeGoneWild excited. They seem of decent quality on a budget
Lcd display died while measuring 30vdc supply. I loved it but unfortunately no long life
Well, my one already stopped working too :D I mostly used it for just resistors and diodes, sometimes voltages, but no more than 24V.
Hi
and i skipped the part where you read the manual
Least the box is not crushed 😅
I got an 20£ auto meter and it's really crap diode function don't work no screen light just dumb led on the back 😅 and it takes cr2032 so I modded it to take 4 AAAs 😂😂
too shine 😂😂
Caption please 🙏🏿🙏🏿🙏🏿
i have problem with my hearing 😄
There's a big piece of dust on your camera lens.
Bro who are you verified is that youtube premium 😊😮
@@Among_us9999 th-cam.com/users/verify
I've noticed, but it's somewhere inside the camera :(
You would be in a coma if your body temp was 40c haha
Not quite, I have had 39.5-40°C fever many years ago from flu. It was pretty bad, but far from coma. COVID only caused 38.5°C to me.
@@mrnmrn1 I was kidding ya nobber
so the only thing theyre good at is stud measurements
Too expensive for what it really does.
It just looks flashy.
It belongs to secondary pollution 🤣🤣🤣

Subject is interesting but can’t understand his language
Used English language
Misused, to be precise.
I still prefer Fluke
It's like comparing oranges and apples
I have a couple of handheld Fluke, a Brymen, an Extech and a cheap Aneng AN8008.
Somehow I mostly use the cheap Aneng. It's small and unexpectedly accurate for such a cheap device.
To be on the safe side I only use it for low energy electronics work. But this caution is mainly due to the fact that I am using the small cheap probes that came with the meter.
The problem of this cheap China garbage is the initial calibration and the long time accuracy! For measurements of uncritical coarse things like the AC/DC grid voltage it maybe okay, but for precision measurements better stick to brand meter like Fluke
Calibration and accuracy? 🤣
ok but this is cheap unit, you cant expect much from it
@Liyang HU yeah, non existent with this kind of garbage
No salt?
FNIRSI makes OK to good stuff for it's price, there FNIRSI DSO-TC3 Digitale Oscilloscoop Transistor (ESR) Tester, is
also a good handheld device for it's price ($50 usd), and more stuff they make.
are you indian?
i am not racist you sound diffrent
