Your channel is pure gold. Hope it keeps growing. I look forward to seeing more of your projects. It would also be fantastic if you could provide a electrician/electronics technician device benchmark table and a reliability/durability rating. I would definitely trust and rely on any information you share in those areas.
Thank you very much for your comment Daniel. Great to hear that you found the video useful. Interesting point about reliability/durability ratings. Let me think on it :)
I got mine yesterday. So far it's looking to be perfect for hobby electronics use. As far as using with high voltage/current, I wouldn't use any random named Chinese meters for that. That's what my Fluke is for.
do the scope in put jacks share a common ground .This is very important to know if one cannel is monitoring a module or an injector that is pulled to neg/ground to operate at the same time using the second channel to monitor a device that has a constant neg/ground . Switching of the controlled neg/ground would be defeated .
Проверьте пожалуйста как ваш прибор работает при измерении большой силы тока (от 5 ампер и выше). Мой экземпляр очень сильно завышает показания (отображает 11,8 ампер вместо 10) и значение силы тока дрейфует по времени (увеличивается со временем). Я подозреваю, что шунт нагревается и меняет свое сопротивление при прохождении через него большой силы тока.
Спасибо за ваш комментарий. Я согласен с вашей оценкой. Учитывая простоту текущего шунта, ваши результаты не удивляют. Я проведу тесты и одновременно буду следить за температурой шунта.
Thanks, nice review. Can you tell me how many kpts the 64kbyte memory corresponds to? Is it the same in all time bases, or is it like 1013d, 1014d? Compared to the Owon HDS272, which only has 4/8 kpts, the pattern was more detailed for the Owon. I noticed a bug with mine that the coupling with the channel remained in AC. I switched to DC but it had no effect. I noticed it while watching a low frequency square wave. after several switches and restarts it worked. One more comment from me. The zoyi was not in DC coupling, so the real wave of the Fnirsi was not visible properly. It was not visible how big the DC offset was.
Thank you, hope the review was useful. I am also trying to confirm what that 64kB memory translates to in terms of sample points. Will give this some focus in my next review. Do you have the Owen?
@@ElectroBananasYT Yes currently i have some, HDS272S, HDS2202, DPOX180H, 1103D, sigpeak dso1511e+, Micsig To1104, Micsig STO2202C and Rigol HDS924S. I was very disappointed with the 1103D when I tested it, it was my first scope, then I bought the sigpeak.😐 sometimes the Fnirsi release something good and useful, but later they destroy it.😱 Fortunately, the SG-004A that I have is good😎, but something was messed up in the later editions, I think they wanted to save money and caused inconvenience to the customers.😱😭 The most obvious is the radioactivity meter, the first series was still good, the others already contained cheaper tubes, they also saved money on the tube voltage adjustment circuit, etc.😡 I don't think Fnirsi is reliable. Owon is not perfect either, they also have bugs in their products, but you can at least notice the higher quality attitude. DPOX180H bugs have not been fixed yet. They know about the faulty part, two capacitors. But it wasn't fixed. They lied in the specifications of the 1013D and 1014D. I intended the 2C53P for my brother, because he is a simple electrician, but if this scope knew what was written about it in the spec, then it would have been very good for him. I've had problems with it so far. 1. AC DC coupling bug. 2. I can't handle the display properly with my finger, probably because it was designed for people with smaller fingers. It doesn't have band control. I mean that the trigger can only be set up on the right side, down in a thin band. The channel can only be moved up and down on the left side. And the trigger time in the upper bar. The measurement can be done in the middle of the screen. Or something similar. sensibly thought through. 3. when I press pause on it and start pulling it apart on the time axis, there are times when the wave does not change and it is not possible to go below a certain magnification. This scope doesn't work like any of my other scopes. I tested the memory by setting the two scopes, the HDS272 and the 2c53P, to the same time base, adding a higher frequency square signal to both. I pressed pause on them and started zooming in on it. I trust Owon, if it says 8kp, then 8k is the point in each time base. I would probably guess 5-10 kp, depending on the time base. It's not 100% accurate, and it's quite an unpleasant procedure, but at least it gives a good approximation. At least more believable than what Fnirsi described. But using the 1013D as an example, the available memory changes depending on the time base setting. And since it can only be saved as an image, it can't be saved in .csv, so I can't count it. not like in the case of Owon.
4. The bug was that the wave could not be moved to the side after the pause. 5. I wouldn't dare to use the part of the multimeter above 400V, it doesn't seem safe. I didn't just mean the fusible fuse, but its entire design. If something goes wrong, and the arc is zig-zagging inside, I don't think the action reaction of Lithium would be funny. Its signal generator is usable, but has a small DC offset that increases with frequency. I prefer to calculate the frequency of a device from the rise time of the square wave signal, using a single trigger, because then there is no chance that skilled programmers oversampling the signal. averaging and other clever algorithms. But this scope cannot be measured that way, only with your method. Anyway, it would be a good scope. It's just that I 6. At a higher frequency, the scope needs more data to calculate the frequency of the wave. My other scopes tell me in a period or two...
Hello, thank you for your very comprehensive reply. And thank you for all the bugs / observations that you have shared. I will take a look at those to see if they exist with the latest firmware when I do the functional review. I would not want to give this to an electrician - they may try and use the DMM on AC mains - I would not trust it. You do have a lot of scopes!!! Your response seemed to be truncated? Thanks again, ElectroBananas
@@ElectroBananasYT If I have some time, I'll try to put some insulation around the DMM panel. 1000V rated huh funny... The thicker green "plastic" adhesive tape used inside the equipments might be enough. i will do wrap around. I also left out why the parameter where there are only two pieces, such as AC/DC coupling, must be set to that rotary crap, why can't it just be a switch or button? I still have to think about the rest, whether it's an user error or a bug.🤔 Yes, as soon as I outgrew one and bought the next one, I kept the older one out of nostalgia.😎 Some are now on loan to a friend. It comes in handy when you can examine two or more independent signals at the same time, and you can solve them with three small hand-held instruments. Of course, this also depends on use. When I just need to look at the frequency change or simple signal distortion, etc. Or when my dear colleague cannot decide with his multimeter whether he is measuring ACV, DCV or AC+DCV. it comes in handy for the cheaper illustrative tool.🤣 I'm really looking forward to your next video, I'm also very interested in your full opinion on it.
In general, the oscilloscope, multimeter and signal generator are not bad. In my copy (firmware 1.7.1.5), the capacitance measurement is extremely inaccurate (1% capacitor 106 pF measures as 33 pF, 0.5% capacitor 6800 pF measures as 6300 - 6400 pF), the oscilloscope measures the frequency of its own signal generator extremely inaccurately. The rest is acceptable for now.
I wrote about it yesterday, but the message was deleted (perhaps because of the link given) ... About measuring the frequency with an oscilloscope: as already written on a well-known forum, the oscilloscope incorrectly determines the frequency of the signal. In my instance, this happens on channel 1, the second channel determines the frequency CORRECTLY! I wonder how it is on your oscilloscope?
@@ElectroBananasYT Yes, this is also on firmware 1.7.1.5. That is, the first channel cannot measure the frequency correctly, and the second one measures everything correctly (I used the FY6900-100M signal generator for testing, with its BNC-BNC cables, the MCX-BNC adapter used a different, shorter one.). By the way, the rectangular signal is still somehow visible that it is rectangular, up to a frequency of 16-18 MHz. After 61 MHz, the oscilloscope almost does not see the signal (well, that's understandable, no one promised us anything else). Well, the multimeter greatly underestimates the capacitance measurement readings (in the lower range, and, let's say, 4700 UF, it already overestimates a little). Apparently, it will not be possible to adjust this.
I know, it is a very big boo boo! Terrible PR for them and makes you question their QA processes. I also don’t like the use of the word ‘Gear’ instead of ‘Mode’ when selecting the mode of their multimeter function.
They have terrible QA and even worst support. They shall put more effort to polish they existing products instead release new one. Saying that, despite all issues with F gear, I did all my hobby works I needed with this gear.
THIS is what I call a diligent and thoroughly review. Thanks!
Thank you very much for your kind comment. Really appreciate it and glad the video was informative for you.
So pleased I found your video. I was just about to order one of these. Looking forward to the performance review.
Hi, thanks for your comment and glad it was useful to you. Yes, it will be interesting to see how it performs.
Thanks for the overview and teardown & hardware review
You are most welcome 🙏
Really enjoyed this video and look forward to the functional review. Enjoy you honest and unbiased viewpoints 😀
Thank you for an awesome review ElectroBananas! Keep them coming.
Agreed!

Just received mine a few days ago. Haven't even completed watching your video. Hopefully it will be a decent performer 😅

Thanks for watching. Well as long as you are aware of the limitations of this device! I always revert to my trusty fluke!
do the scope in put jacks share a common ground .This is very important to know if one cannel is monitoring a module or an injector that is pulled to neg/ground to operate at the same time using the second channel to monitor a device that has a constant neg/ground . Switching of the controlled neg/ground would be defeated .
The multimeter inputs are isolated from everything else. However the scope inputs, signal generator output and USB share a common ground.
@@ElectroBananasYT thanks. that's very dangerous if a person does not know this before they start to do testing
Potentially yes, I agree. I do cover that in my video.
Thank you. It would be nice to have 2C53P only detailed test.
Thank you for the feedback for the upcoming functional and performance test. Much appreciated!
It would be nice if you got this (or another) oscilloscope and didn't expect the test result.
