Hi! I'm Hugo Ferreira an electronics lover that like to make projects and share with you. I review a lot of test equipment to show how they work and what you can find if you buy one, but as always, from the point of view of a electronics enthusiast and hobbyist always eager to learn new stuff and share it with you.
On my reviews, you can always find the information that I will need when choosing something to buy, so you can expect to find videos with a lot of information and detail in each review.
You're awesome for supporting my channel! Kudos.

Thanks for considering me for feature your product.
Hi Hugo, question... I own this oscilloscope. When I press and hold the "auto" button I get a message that reads "awaiting auto correction" at this point all of the buttons freeze and I cannot get the oscilloscope to respond unless I reset the unit.. do you know how to get this to work or get out of this mode? Thanks!
Thanks for the nice video! I am quite new to the field so please excuse if this is a stupid question. I was under the impression, that the amplitude of 3.6 V shown at 32:07 is the peak-to-peak amplitude, as on the device itself it also says 3.6 Vpp. However, the plot in the software shows a wave from -3.6 V to 3.6 V. Is this a mistake in the software-plot or am I missing something? Thanks in advance :)
Hi, I think you're right and that might be some kind of bug in the software, since even if it is really small, on the oscilloscope you have 1,8V +/- in the VPP section, second square on the bottom. But nice catch. Thanks for watching.
Good morning. My name is Marco and I'm Brazilian Your video is very good. I have a question: This ZT702S device, with the oscilloscope function, can I connect it to a computer for measurements, making the computer screen the oscilloscope screen? Another question: can I measure 1mV scale, as I use a lot of load cells? Thanks
Hi Marco, no, you can't. That functionality exists in desktop oscilloscopes, but not all of them have it. Rigol for example allow you to do that, but can't say of all other brands, you can do that for example with the Zeeweii DSO2512G ( ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-yh4s4-BT5-8.html ) and also with the DSO1511 also from Zeeweii that have an AV output, I think that in the small factor those are the ones. Thanks for watching.
Se quemó un LED verde del power no me deja usar el táctil de la pantalla para entrar en los menú. Se me complica reemplazar ese LED le puedo colocar una resistencia?
Please help me, I have a USB tester like that too, but when I input it with a charger, the FNB48S screen is already running Amps and watts (6w) while I haven't installed a load on the output, and that makes my FNB 48s immediately heat up to 80° C+. is there an error/shot on my Fnb 48s and How do I fix it? For QC/PD testing, it's still safe, there are no problems. The main problem is that when the input is plugged in (no load), the heat on the FNB increases drastically, until white smoke comes out. please cooperate and help
Hi, your device is clearly malfunctioning. You should enter in the whatsapp FNIRSI support channel and contact them to replace your unit. Thanks for watching.
Its too bad you didn't test the USB power plug for volts/amp test, lots of time they sell a 100W USB when if you test it, its more like 20W. If that is the case, the slow heat-up time or 10seconds should be more like 4 seconds if you used a different power supply. That's what I'm thinking. Not enough amps.
Hi Jeff, It's not on the video, it was me playing around, but I tested with the 65W delivered with the HS-01 and connected also to my Rigol DP831 power supply 20V/3A and no difference. Now that you talk about it, it will be a neat thing to have on the video, sorry for this fail. Thanks for watching.
It's a pretty lame soldering iron. Where're the 65W? Even a very cheap Quicko T75 performs better and has no stupid animation- due to a missing display ;-). (edited: typo) Second edit: It performed very well in the “SDG Electronics” test. Apparently there is a problem with your setup or copy.
Hi, lame is a bit harsh and I think Quicko T75 uses the T12 tips, on the same tips the HS-01 has very nice performance. If I have something to point out, is just the time it takes to get to the temperature, it is accurate, but take a bit more than I was expecting. Thanks for watching.
@@TechCornerTV Sorry, but something was very wrong with your setup. Either the USB tester causes some issues, the power supply, USB cable or the iron you received itself is screwed. Take a look at SDG Electronics review and peak power draw. With a known good supply he measured up to 80W on high thermal demand boards and the coin test.
Hi, I had to see the video to understand that comment 😁 I made it a long time ago, and it really was a "kickass" capacitator (in pt we call it condensers), very nice power linear power supply. Most of the PS of this size are switched. Thanks for watching.
Hi... ahahaha.. good example! For what I know, this was one of the first units, the units getting to the market right now are ok. But you got a big point. Thanks for watching.
@@iblackfeathers thank you so much I really do mean that.. For like soldering wires for drones battery what one would you say would be more suited please
Hi, the T245 should be enough for that kind of work. T245 is more for the everyday work, while T210 is more dedicated to soldering very small components and only an example, can be used to solder 0402 smd components. Thanks for watching.
@iblackfeathers Thank you for clearing that out. I did ask to FNIRSI, but the answer was related with the tips (they're right) but sent me a photo of the tips head like the K, KU, I, B, C2, and so on, but didn't clarify that we had a different model of tips. So glad you were able to clarify this. It was my initial suspicion, for different T245 tips you'll don't need a different solder iron model. Thanks for watching.
When you are testing millivolts, be aware the millivolts range is selected manually using the range button. You had it on "Auto" range which does not switch to the mV range.
Hi, I think you're comparing apples and oranges 😁 for me, the et120m is a more complete solution and with a higher bandwidth support. This doesn't make the 154pro a bad device, not at all, for the category it is comparable (dso150, dso152, dso153, dso138) is in my opinion one of the bests. Thanks for watching!
The FNIRSI scope does not meet its basic specs. Instead of 1G samples/sec and 100MHz, it's 200M samples/sec and about 30MHz. See the learnelectronics review for more details.
Hi. Thanks for the review, I'd like to add a few things. For such devices, it would be worthwhile to include a disassembly part in the video, because the multimeter part of the Fnirsi is a disaster. Fuse doesn't have a case, but small glass fuses soldered in, the panel of the multimeter part a few centimeters away from the main panel, without any insulation. Because of the ranziens, I wouldn't even dare to measure the mains 230VAC with it. The part of the multimeter is imprecise, you are better off buying a Zoyi multimeter and a separate hand-held oscilloscope. The only thing I really like about it is the trend bar.🥰 So much for the oscilloscope part. The amount of memory is not properly defined, it is not possible to know how many memory points are actually used. If the sampling is stopped, you cannot zoom in properly, each time base has a value after which the wave does not change, but you see the time base decrease. It takes a lot more samples to measure frequency than any of my other scopes. More at higher frequencies. Handling it is difficult if you have large hands, I often manage to shift the wave or the horizontal position of the trigger when I want to adjust the tension of the trigger. The rotary parameter setting is brain dead. You can't wrap it around, but you can see it in the graphic. With two settings, why not a smooth switch? AC/DC, CH1/CH2 selector for trigger. etc. The single trigger function only works with a slower time base. I tried to do it, a frequency limit measurement that I think is much more effective. When you measure the rise of the square signal. And you count on that. But this is not possible because it does not allow a single trigger with a fast time base. If I remember correctly, under 2ms, I'm not sure about that. This is a huge drop from the DPOX180H. There is also a start/stop button at the bottom, which is easier to use than the small arrow in the upper right corner of the screen. And your signal generator is garbage. He can't keep the frequency, there's a little wobble. At the higher frequency, a DC offset is included. Positive variable value output only, not normal AC. You can't shift it with Offset either. I think what you saw as a shadow was a setting error on your Rigol. The signal is very noisy. There is distortion in the signal at 1.6V. All in all, it's a trap, well worth the price. This is the category where you should save more money and buy a normal usable one. Even if it costs 3-4 times as much, it is much more worth it. for example.: Hantek TO1112D costs twice as much, but does much, much, much more... and only twice as much... or Zoyi multimeter + stand alone signal generator + Hantek TO1112. This can be three or four times as much, but in return it is three separate devices. Compared to the Fnirsi, you'll have an awesome multimeter, an awesome signal generator with two outputs, and a lot more features, and you'll have an awesome oscilloscope.🥰 You can use them in several situations at the same time, if something goes wrong, not all three devices go in the trash.🤣
Hi! First and foremost, I would like to thank you for the time you spend and dedicated in this comment, really appreciate it 🙏 you touch a lot of valid points, but two stand immediately to me 1) "This is a huge drop from the DPOX180H." - agree! The DPOX180H really raised the bar and in terms of oscilloscope is for me one of the best in portable form factor, that's the way they should follow. 2) "Even if it costs 3-4 times as much, it is much more worth it." - I get what you're saying and to be honest, I kind of have the same filling. But one thing I understood is, that I am privileged and for me, I prefer to buy ONCE a more expensive equipment (I did with my Rigol oscilloscope, power supply and signal generator and a siglent multimeter), the problem is, there is a lot of places and situations where this device will be enough. for work or hobby, only the viewer will know if this will fit their needs in terms of 1) tech specs or 2) and most of the times, the budget. All summed up, you have a point in most of your notes, thanks for watching.
@@TechCornerTV I don't know if there are any restrictions on the length of the video that can be uploaded by RU-vid, but I think a few minutes would not affect the viewer badly. I remember when I watched a 5x40-minute teardown video series without a break. In that case, I would agree with you if this scope knew what was described in its specifications. But the multimeter part is inaccurate. it was complained about in one of the posts, so i tested it. Unfortunately, there is a drift when measuring current. The part of the signal generator is garbage, 3V max and no offset can be set on it. In addition, the quality of the signal is also rubbish. its frequency is not stable. there is some garbage between the start and end of the wave. The oscilloscope part is also unreliable. there are many restrictions. which is meaningless. single trigger limited only above 2us/Div. After stop the signal with the single trigger, you can't zoom in. The time indicator changing but the signal doesnt. If you stop the signal in normal or auto mode, you can zoom in, but somtimes the signal distored. 10Mhz sine signal need more than 18 period for frequency measurement. 1,5Vpp+0.75V offset 10Mhz signal in 200ns/div show a 2Vpp signal. in 80ns it show 5.5Vpp. and the signal distored a little. unreasonable function, 20MHz BWlimit for a 10Mhz scope why? BTW the limit doesnt work. i try with a 10Mhz square wave signal... "Built-in SDRAM, real storage depth" really funny... Haha You can only save images, not csv files, which is no accident. Otherwise, it would turn out that the promised 64kByte, which should mean 64,000 samples for an 8-bit scope, is not nearly as much. Owon saved 8000 samples, and for real. I compared it with that, and my intuition is that it doesn't look better than 12,000 samples. I currently have 3 fnirsi, 2 owon, 1 sigpeak dso1511e+, 2 Micsig and 1 Rigol scopes. The three Fniri are 1013D, DPOX180H and this is 2C53P. I cannot agree with one of your commenters that one always needs 4 channels, because in most cases 1-2 channels are more than enough. At least the channels don't always have to be in sync. two two-channel scopes are often better than one 4-channel scope The first thing I bought was the 1013D, and two weeks later I bought my first Micsig scope... after that I needed a smaller handheld scope. I bought Sigpeak and an Owon because of the +signal generator. Later I wanted to replace the Sigpeak with a two-channel one with a larger display, so I bought the DPOX180H I then ordered another Owon... I just ordered this 2C53P for my brother. And I'm currently looking for another brand at a reasonable price, maybe Hantek... I gave Fnirsi a chance to prove herself several times... What I wrote before is still valid, because if someone might need this inaccurate and unreliable tool. For which Fnirsi will perhaps release one or two more updates and then start selling another series and forget about this series. He'll be in an awkward position later if he needs more. I don't have the guts to sell the 1013D to someone else, DPOX is just usable. I still don't know what to do with this. I'm waiting for the latest update, I think they'll deal with it this year and then put it in the deep end like DPOX. if it will be usefull, then I will keep it to measure battery voltage, I really like the trend bar. Thank you for the video and the opportunity to say what was on my heart.🥰
@@juhaszpeter4796 "10Mhz sine signal need more than 18 period for frequency measurement." --> In my copy of the oscilloscope, it is almost the same, but only on the 1st (first) channel. on the 2nd (second) channel, the signal frequency is determined correctly, regardless of the number of periods on the screen. Please check this on your oscilloscope. The built-in multimeter works well, except for measuring capacity - it understates the readings.
@@ivanyou5795 Thanks, I just tested it and it's the same for me too. There is something wrong with each channel With the multimeter, I only checked a couple of voltages and recently, at the request of a colleague, the current. I prefer to use an LCR meter for capacitors and other components. The voltage measurement was not as accurate as my other multimeters. 9 owon, 2 aneng, 1 rigol, 1 uni-t. due to its physical design, I wouldn't really dare to use it in conditions where large transients may occur. During current measurement, the value increases continuously. the higher the current, the faster.
Hi, that's so cool to know. I did download after the video as made the 1.3.8, but didn't have the time yet to install it. Thanks for sharing and watching.
Thank you for the review- was looking for a recording 2ch usb scope- (Hantek ??), but saw this super useful hand DSO-152, and then luckily found this DSO-153 review. Have just ordered a DSO-153 on the strength of this video, to work on my cars and bikes (old bikes, new electrical gremlins !) ;)
Hi David, totally understand, that's why I put the chapters in everything, so the viewer can choose what he prefers to view. Some people love it like this, some don't, but I do get what you're saying and really appreciate your feedback and the time you spend to write this message. Thanks for watching and the comment. Take care.
я ждал проверки точности в режиме измерения силы тока от 1 до 10 ампер - не дождался. Мой прибор врет при токе выше 5 ампер. начинает завышать показания, чем выше ток - тем сильнее завышает. Хотел узнать что там у других, но увы, автор обошел эту проблему стороной
Hi, it was not really avoided, I don't usually do Amp measuring on my reviews, you can see any other review of multimeters made by me. Sorry for disappointment, but working on a setup that will automate these measurements. But it is nice to know of this problem, thanks for sharing.
Yes, mine too. I could only check it with DC current, but it starts to overestimate even at 5A. At 6A, it went up by 300mA in 1 minute. rises faster at higher currents.
От этих проблем не уйти. Мой экземпляр сильно занижает показания при измерении ёмкости (я тут сильно не "парюсь", поскольку дома хватает точных измерителей RCL), и, на 1-м канале, толком не измеряет частоту сигнала, а 2-й канал - измеряет правильно. Все равно, мультиметр тут неплохой - я, вместе с этим, купил себе еще Hantek TO1152D, так у него мультиметр еще хуже, несмотря на то, что он стоит в 3 (три) раза дороже этого. There is no escape from these problems. My copy greatly underestimates the readings when measuring capacitance (I'm not really "steaming" here, because there are enough accurate RCL meters at home), and, on the 1st channel, it does not really measure the signal frequency, and the 2nd channel measures correctly. Anyway, the multimeter here is not bad - I, along with this, bought myself another Hantek TO1152D, so his multimeter is even worse, despite the fact that it costs 3 (three) times more expensive than this one.
Hi, not sure what is the battery duration, what I can say is that arrived fully charged, recorded video with it always on for about 6 hours and it lowered 1 bar on the battery indicator, so pretty cool. Don't know in real work environment how much it will last. Thanks for watching.
Preciso de chorar um multimetro novo ao patrão e uma thermal cam para substituir o vaper com pedra de rosin que uso para detectar os curtos nas motherboards... E olha o que encontrei? 2 em 1 😂 Patrãooooooo Top review 💪🏻💪🏻
É um kit imprescindível para quem utiliza tanto de forma profissional como doméstica. Desde a ligações do forno/placa, extensões elétricas, toda a ponta de fio multifilar ficam super seguros, em vez de estar a enrolar com os dedos e depois não caber no buraco 😂😂 não prescindo do meu, e quando empresto digo: Tem 4 V's 😂😂😂
Olá Hugo, passando para ver os teus vídeos!! Utilizo um da Xiaomi quando estou naqueles dias aborrecido e não apetece desapertar e apertar manualmente 😂 Até da jeito! Continuo é a achar que as pontas deviam ser revestidas a Chrome Vanadium. É a única parte negativa que acho desses kits 🤷🏻
Olá Ricardo, que bom ver-te por aqui novamente, concordo, mas olha que as pontas que aqui tenho não são mazinhas. Nos testes que fiz (não filmados) houve ali alturas que falhei um pouco nos parafusos e não tive o minimo dano nos bits, por isso, já não é mau sinal. Obrigado por assistires.
Hi, as we usually say, something gotta give. In this case I think it is a balanced device in terms of price vs features. 4 Channel is asking a bit, but I think miniware has a small device with 4 channels, is the only one I can recall at this moment. Thanks for watching and commenting.
For me, on the contrary, 4 channels are often irrelevant. the 2x2 channel is better for me.🥰 It depends on the situation, who does what.😎 I work more with dependent signals, where the channels don't have to be in sync, so it's no problem if you look with two separate hand-held oscilloscopes. Sometimes you can watch three channels in sync, only then the two two-channel scopes must have a common channel with the trigger. so I was able to look at the starting curve of a DC three-phase motor. I didn't have to pull out the larger desktop scope.🥸 I agree with more memory, but with this Fnirsi it has not yet been proven that it uses as much as it is written.💩
Seems like all the 'budget' test equipment is multifunctional. More and more half decent tools are crammed into one box. Instead of dedication to one function. Take the dso3d12; why would you want to make a conversation with your scope/gen/DMM? 😂
Hi, I agree with you! I don't get what all manufacturers decide to transform everything in multifunctional devices... not only the small ones, Owon know has a desktop oscilloscope with multimeter (to be honest they have some models like that for quite some time) but release recently also a power supply with multimeter and the Infrared camera from TOOLTOP too. This one is well achieved and will be a nice addition to a hobbyist equipment list, but I also wish that if do something really well, it will be better. But again, in this case, it's not bad at all :) Thanks for watching and your comment.
The signal generator + oscilloscope makes so much sense that if you want to drive something with a basic signal and it's not a problem that they are on the same circuit, you can do it quickly with one device. Some people have made an I-V curve tracer connection line for it. The multimeter part is only a plus if you don't use it as a scope all the time. The Owon came in handy a couple of times when we measured and couldn't decide what the hell it was.🤔 But this is only worth something if it is reliable and accurate. Fnirsi has neither..🤣 The power supply with the multimeter function is really great, the only drawback is that if you draw a large current from it, there is a chance of a slight drift on the multimeter. But regardless, it's great that you don't have to take out a + instrument if you just need a quick measurement. The display is split, you don't need to switch, so it's more convenient to use. Only its noise and the noise of the fan at high load are a bit disturbing.
Oh no, they misspelt function, they wrote it "Funcation". That would drive me crazy seeing it every day. If they cant spell right on the outside of the chassis, it doesnt give a lot of confidence about the internal components. Damn, why you do this, Fnirsi?! I want to like that company, I have many of their products.
@@shaolin95 It's a shame, because they are on the verge on being seen as a serious company, but then they make HUGE mistakes like that. Come on, dammit...
Hi, I'm so ashamed for not noticing that in the review... my head exploded when I saw this comment. I reported already to the FNIRSI team. Thanks for sharing and watching!
Honestly, I dont get this. If someone thinks they need a scope, they probably have a multimeter already. Nothing is for free, if they give a multimeter in the scope, they are making a compromise somewhere, and probably are increasing the product's price too. I see you have tested all FNIRSI tools; of their scopes which would you recommend for a home working space?
Hi, if you want something really good as scope from FNIRSI, go for the DPOX180H. I think they nailed that one as a scope and for me, from FNIRSI is the best scope, in terms of accuracy and bandwidth support, really nice. This one will be a nice option also, very good multimeter, but on the oscilloscope has a lower bandwidth support, but that might be enough for your usage. Thanks for watching.
@@TechCornerTV Yeah, I havent checkout in detail their handheld ones. I will, but their screen is too small for me. I think the 1014D fits my needs best, since I dont plan to take the scope out in the field.
@@eraldyllido not do it. you should look it up, there are many videos on the net and it is worth checking out the blogs as well. Fnirsi lied a lot about the 1013 and 1014 series. DPOX is more useful, but has some shortcomings.
I have to say that the DSO3D12 is much better as it includes one very important feature that i don't think was covered in your guide: it has a frequency measurement of up to 4 decimal points, which I needed to measure the DS3231 32.768Khz square wave.
The depth of this memory is 128kb, with a good chance of a maximum of 16kpoint samples for an 8-bit scope.🤔 If the multimeter part and the signal generator are not important, then the Hantek TO1112 is better. It has less sampling but much more memory. I don't know how many Bugs there are, unfortunately I bought this Fnirsi instead.😭
The DSO3D12 has a much worse signal generator - there is no amplitude adjustment of the signal. In this case, the signal generator did not seem very good at first, but after changing the complete wires to good ones, I was satisfied with it. Moreover, it outputs all signals with a frequency of 10 MHz.
Excellent presentation I was really hoping to see a signal gen in the scope, but it looks not so good. The other features look ok. I have several FNIRSI mini scopes and they do fine. I really need a good sinewave gen for transistor experiments. Can you show something on Function Generators, I currently build a circuit for each freq. a push button gadget would be nice.
Hi, the weird part is that it started very good and in some point, started to have that weird behavior, really strange. I think that is some kind of firmware solvable problem, let's see. Thanks for watching.
