Hi, agreed. Thanks for watching!

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 KZread, 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.🥰

Please check this on your oscilloscope. The built-in multimeter works well, except for measuring capacity - it understates the readings.

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.

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.

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.😭

@ivanyou5795

Ай бұрын

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.

even it looks very nice i'm sooo *not* into this INTENSE screen touching to get some of the basic settings...

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?!

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.

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.

What is FUNCATION?? What's wrong with FNIRSI? This a major quality control problem. Can you imagine if Fluke mis-spelled their label "PUKE".

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.

2 channel is just not enough... I'd give up some bandwidth (some...), but I need 4 channels and reasonably deep memory...

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.💩
