You are most welcome, thanks for the comment.

Hello Derek, thanks for sharing that information. That is a surprise. I also have a TC1, I will try it with some OC71s that I have and see if I get the same results. What version of firmware do you have?

Thanks for the compliment and glad to hear that you are not having the same kind of knob issues! The antenna video is in the queue. Will release it as soon as I can!! Thanks for watching 😊

@@ElectroBananasYT I look forward to it. Many thanks for the reply.

I think this was an issue with earlier versions of firmware, before you upgrade, please refer to my reply to the comment from wogalwogal. Thanks for watching

@@ElectroBananasYT a firmware update did it!

Very happy for you 😊👍

Hello, thanks for sharing this information. The battery like on mine was not that bad. Yes this scopemeter has a lot of limitations.

Yes I think they probably come out of the same factory. Agree, I find it works much better than expected.

I have the Kaiweets iron - I love it!! amazing fast to heat up. It has replaced my bench iron :)

Hello, yes I think it would be a good fit for a hobbyist in these situations.

@@ElectroBananasYT Thanks for that🙂

@@taxineil1 Most welcome

I agree that it would be a good fit, but if you don't know what you need it for you definitely shouldn't buy it.

Hello, yes. This can be changed from Menu->System Settings

@@ElectroBananasYT Thank you, I didn't scroll down far enough.

I thought that too. But I think the real reason is to stop it vibrating all over the place. The bass is quite powerful and without extra weight it goes exploring! 😅

Thank you. It was fun making that video. Thanks for watching 😊

Hello, the USB port is isolated from the Multimeter section, but not the oscilloscope.

The XY function cannot be used from a Computer.

Hello, that is a big topic. Suggest you search for ‘testing components with multimeter’ in TH-cam

Hello Jaime, really glad the video was helpful to you. Thanks for watching 😊

Hello, there is a secret calibration function (it is in my video at the end), but it is only intended for use by FNIRSI during factory calibration and there are no instructions on how to use it - so don’t!!! You might uncalibrate your device!! The multimeter does provide slightly different reading sometimes, especially with ac / fluctuating voltages as the multimeter attempts to give RMS values. Were you measuring DC?

Hello, it should last 6 to 7 hours. Refer to the current consumption test in my hardware review of 2c23t at the 38:30 mark. th-cam.com/video/L8-KsOObSY0/w-d-xo.htmlsi=8_FU_l1tizvvcI4v

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 :)

@@ElectroBananasYT thank you again for your content and hard work

Thank you, glad you found the video useful.

Hello, that is strange. Mine holds charge well when the power is off. The only time I lost power was when I was carrying it in a bag and the power button was accidentally pressed (it is not recessed or protected from accidental pressing). It only uses 5V charging and can’t charge at higher voltages. Sorry to hear of your troubles. Perhaps get in contact with FNIRSI, they are quite helpful.

Muito obrigado pelo seu comentário gentil. Fico muito feliz que você achou o vídeo útil. Você viu meu outro vídeo sobre a modificação para adicionar uma entrada de antena? Espero que você aproveite seu novo rádio 😊

@@ElectroBananasYT eu vi sim, espetacular é uma aula, pena que eu não tenho o conhecimento que você tem para melhorar a captação do sinal, assim que eu receber o meu rádio, eu volto aqui para lhe informar.

Certo, ótimo. Eu planejo fazer um vídeo mostrando como melhorar a recepção de ondas curtas usando componentes reciclados simples e sem ferramentas especiais ou solda. Só preciso encontrar tempo...

@@ElectroBananasYT show de bola

Hello Cristian. For a general purpose portable scope meter, I totally agree with you. I would choose the 2C23T and save some money.

Hello, output voltage can only be changed in 0.1V steps. So the lowest is 0.1V.

Thank you very much for the kind comment, glad you found the video useful. Yes the radio is great fun and sounds great for the size of the enclosure. I am making a video on how to make a DIY loop antenna also. Hope to release in the next couple of weeks.

@@ElectroBananasYT awesome and I'll be looking forward to that

Very well done. Thankyou.RON Z. WA3090SWL

Thank you Ronald

Thanks for watching. Well as long as you are aware of the limitations of this device! I always revert to my trusty fluke!

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.

Thank you for watching

どういたしまして。動画を興味深く思っていただけて嬉しいです。私は古い日本の技術が大好きで、カシオの電卓はとても信頼性がありますね！

Hello, my original unit is working well and I enjoy using it. I accidentally cracked the plastic screen, however FNIRSI sent me a replacement. Other than that all good. I also bought a protective pouch to carry it around in.

Ok, I’ll probably make the purchase. Appreciate your feedback👍🏻

Hello, my original unit is working well and I enjoy using it. I accidentally cracked the plastic screen, however FNIRSI sent me a replacement. Other than that all good. I also bought a protective pouch to carry it around in.

Thank you for sharing this information. I am seeing similarities during my tests.

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?

Thanks for this. How unusual! I will finish my tests this weekend and will let you know. I assume this is also with firmware 1.7.1.5?

@@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.

Thank you Ivan, I will compare with my results

Hi, thanks for your comment and glad it was useful to you. Yes, it will be interesting to see how it performs.

Agreed!

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.

Good point, although given the type of buzzer, they may be limited by what can be done to control the volume (hardware limitation).

Thank you!🙏

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?

Thanks also for sharing the bug on the coupling, I will see if mine has the same issue.

@@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.

Perhaps some of your husband’s chores require him to have an oscilloscope? 😅😅??

Thank you! Yes, that cat always wants to be involved in everything I do! 😺 73 from the cat.

Thanks for your comment. Let us know how you get on with it!

Hi Barry, thanks for the comment and I am glad that you found the video useful. Wow, that is incredible value - good catch!

@@ElectroBananasYT I note your insightful use of the word "catch"😂 The "catch" was, after seeing your presentation, learned of missing items: my unit arrived in a plain box with no nice instruction book and the serial number label missing but hey! it all works. I also note the 4051 shift registers still being used, more than half a century! I still have my red Motorola 4000 CMOS data book from 1976. I also note your Tandy Realistic AM radio - you are a blast from the past and present Sir!!

Thank you Barry! Well it is still an amazing deal! And good to see those old logic IC’s still being relevant today. Yes I like to mix modern with retro 😅

Hello, glad you found the videos useful. YOU MUST BE VERY CAREFUL IF YOU INTEND TO UPGRADE THE FIRMWARE. As of May 2024, I have this following information: Firmware V2.0.2 is only intended to fix issues with an older version of hardware. If used on the latest version of hardware, the upgrade will fail and the device will not start - you will have bricked your device. I think this is why FNIRSI took down the firmware from their website - I suspect that there were many users bricking their devices by trying to download load 2.0.2 to a device with a newer version of the hardware. To determine if you have the ‘old’ or ‘new’ version of hardware, go to settings and see if you can see the hardware version displayed (hardware may be V0.4 or later). If you cannot see any hardware version, then you have the older version of harware. If a device already has the latest version of hardware (V0.4 as of May 2024) a firmware update is not required as it would have been shipped with the latest version of firmware for that hardware (V2.0.1). If you have the older version of hardware, then you can upgrade the firmware to V2.0.2. I know, very confusing. If you have bricked your device, contact FINIRSI by email / whatsapp. They are usually responsive and helpful.

Thanks for your answer, dear friend. Yes, you're right, this is a mistake. I only have 2.0.1 written. Does this mean there is no need to update? Thank you.

Hello, if you don’t see a hardware version then that means you have the old version of PCB. And this means you can update to V2.0.2 (as I understand it from the various blogs on the topic).

Please send me the file with firmware 2.0.2. Thanks a lot

Hello Lucas, thank you for sharing this important information with us.

I do have the same problem on my W7 pro PC it does not work, asks always to format the file in FAT16 modus. I will try it on my W10 PC .

It works on my W10 PC ok!

@@lucasbretels Thank you for confirming that.
