I bought this for my husband after watching your review:-) Happy husband = happy wife 🤪.

I ordered a FNIRSI 2C23T about a month ago but didn't play with it until watching your videos. Thank you for taking the time to make these videos, it really helped to understand how to use it. Also your videos helped to know what quirks to look for and possibly accuracy issues. It is a fun little unit to play with and certainly the one to take on the road when wish to do items away from home. Always take two multimeters with me, so this will quickly become that second multimeter with the bonus of having an Oscilloscope and function generator. Thank You.

Thank you for your diligence. You really do deserve more subscribers.

I just ran across your channel and immediately signed up. Honestly, you deserve many more subscribers. I'm one of those who admires your unbias reviews.

I am considering buying this piece of equipment and must say your detailed reviews and teardown were very well done indeed, and invaluable! Compliments sir! Let's see if they can actually deliver them...! Cheers from Connecticut!

Super useful video! Just got one! It's pretty nice for the cost! :) I was stuck on where to start on how to operate the multimeter and got lucky noticing the secondary function on each button which allows you to navigate the multimeter features.

Mine should arrive any day now. Great video, now I don't have to figure out how to use it on my own. I buy all this new equipment, It is so cheap and fun to explore, I just received my new ZEEWEII scope/meter and it is fantastic. I will use both meters in my garage for testing everything I need to test.

Fantastic performance review!!!

You're doing the lord's work here, thank you!

I ordered one of these after watching your first installment, the shipping date keeps getting pushed back as they are out of stock. Good honest review.

Many thanks, I did buy one of these and think that for the price it will suit my needs well. I only really wanted a single channel and working on voltages less than 24V DC, so this is fine for me as a hobbyist. I see what you mean for higher voltages on the Oscilloscope side of this device, but I think if you are working with such voltages, you would pay a little more and get something more suited to that line of work. Many thanks for the great videos and I will look forward to more in the future. Take care and stay safe, Joe

This product is starting to become very popular. As a third video, could you show how to use this oscilloscope to find or measure a faulty component on a power supply, a modem or a computer motherboard? I'm sure this will guide novices like me and enable you to reach more followers. Also, I would appreciate it if you didn't forget to add subtitles. May the strength be with you.

I got mine from Temu special offer £34!! At that price I had low expectations especially at low current and the 'scope. I use it for automotive applications fuel injector pulses, etc where it really is in its comfort zone. At just over £30 or £80 full price it is a fantastic package! Thanks for the additional info on screenshots and firmware upgrades, etc.

After looking at this video I ordered one. Primary reason was that I needed a decent multimeter. Not much extra cost for added functions. Had a Fluke Scopemeter thirty years ago which was very useful when working with industrial automation. Now retired though sometimes an oscilloscope could be useful.

Great video, both actually . I found your videos after ordering mine . I'm waiting for it to arrive. I am curious after watching your tear-down video if I could 3d print a new topper to expose enough room around the BNC connectors to take shielded probes. Then again maybe I wont as a way to remind myself to avoid high voltage, maybe. For me it's a huge gain of space on my desk in the house and I can move some of my other kit to the shop. Now if only they make one with a multi CH logic probe packed in with data logging out to PC. LOL That would really clear my desk in the house.

Very good intel and excellent video

picked one up. only tested the multi meter but my unit is whiten .3% of NIST traceable equipment. Temp is off a little but withe spec for the setup. Overall nice little unit. Also you can replace the boot image to whatever you want.

저도 구매를 하여 사용중에 있는데 매우 유용했습니다 가성비가 훌륭 하다고 생각합니다 😝 Review가 많은 도움이 됩니다 감사합니다 Channel을 열심히 구독하고 있습니다 좋은시간 되세요

Amazon $90 FNIRSI 2C23T 3 in 1 Handheld Oscilloscope Multimeter DDS Generator, 2 Channels, 10MHz Bandwidth, 50MSa/s Sampling Rate, 10000 Counts, Voltage, Current, Capacitor, Resistor, Diode Test. The X-Y mode would have been a nice feature. 😎 Thank you, great video.

Thanks for your help and

Thanks for your

Great review. Did you do the undocumented maneuver after taking all the measurements/eval? And do you thing the Red battery level affected anything? Amazing what they are doing with these handhelds. I have the Zoyi 702. 👍

Great video! I ordered one.

Thanks for the review. What do you think comparing this model to Owon hds272s? i know Owon is double the price but Fnirsi is far from the performance of Owon? Thanks

First of all, thank you for these 2 videos about this product, my question is if there is software for PC and connecting the FNIRSI to the PC's USB. Thank you. Greetings ​

I was able to use an android phone to send the firmware update to the oscilloscope which was not expected to work but it did and very very quickly too.

got it for me and my dad, using it just for simple component testing in cars and so on where the stationary is impractical or a bit of a overkill.

Thank you very much for the review.

Thank you for the excellent review. I would like to use two channels to input a 20khz square signal and use the second channel hooked up to an antenna to receive the same signal and measure any frequency shift and to measure the decay. I will boost the signal with an audio booster circuit and transmit the boosted signal. Is this possible? Thank you for your time and efforts tgst you have spent in my behalf.

Would you recommend this for 40hz 10-150v ac The usage would be setting gains on car audio amplifiers using the oscilloscope up to where the sine wave starts to clip. Thank you for a thorough video 🙂

Do you think a firmware update can fix the jittery / inaccurate in dual channel mode?

Excellent review, thank you for your work and your time. I have the same one, firmware 2.0.1, do you think it should be updated to 2.0.2? Thanks a lot.

Thanks for the review. I am looking for a small decent oscilloscope to test sensors on cars, such as cranshaft sensor, camshaft sensor, oxygen sensor etc etc. Is this good enough to do that do you think ? Or is it overkill ? Suggestions ? Thanks

Just now I got this 2C23T but one thing I found: the volt value that write on oscilloscope screen less than input but the drawing is correct , input is 5.000 V and the multimeter mode is correct and drawing wave on oscilloscope is correct but the value write on oscilloscope is 4.800 is there a way to calibration ?

Do you know what maximum current the signal generator can emit? 20-30mA? Is there any over-current protection?

Very nice tests and points made. A bit dissapointing on the square wave and the Nano test. This last test put it more on the toy side ..... Have you tried the Zotek 702 ?. I do audio repairs and some SMPSU repairs, probably good enugh ... but lacking XY ?? ..... COME ON !!!!!

Thanks for the two great reviews. After looking at them I decided to buy the device. But now I have a problem. When trying to update the firmware, the device rebooted to 100%, but then it didn't turn on anymore. I wrote to support. Can you advise what I can do?

Can the function generator output voltage be adjusted down to the milli-volt range like 0.0025 v and 1kh frequency?

Hi, I’m considering purchasing one of these, but was wondering if the one you have still works to see how well it lasts. Could you give an update on that?

I'm looking for specs on vertical resolution....8 bits?

Hello! Great video, but I have one problem..I can t find anymore the 2.0.2 firmware update on fnirsi official site. If you can help me..thank you in advance!

Thanks a lot for this video. . . would you share the update V2.0.2 ? . . . is not longer in FNIRSI Download page :(

At 46:26, the user manual for dual channel usage states: "When dual channels are used simultaneously, the ground clamps of the two probes must be connected together. It is strictly prohibited to connect the ground clamps of the two probes to different potentials, especially at different potential terminals or 220V of high-power equipment. Otherwise, the oscilloscope motherboard will be burned because the two channels are grounded together, and connecting to different potentials will cause a short circuit in the internal ground wires of the motherboard, as is the case with all oscilloscopes." Is there anything you may have forgotten or missed?

Dear sir, I would like to use FNIRSI 2C23T for component test , but i don't understand , please help me thank you very much

FNIRSI actually delisted the 2C23T from there Website a day ago. The question is why and wether it is still in production.

Thanks! XY mode yet?

@ElectroBananasYT After your review I ordered this from Amazon for $79, it will be delivered by tomorrow, let's see if it is a good addition to my tools.

hi ty for the brill fnirsi 2c23t video's ,, but when i update it it does not reboot ,, i sent it back ( to amazon ) and the same thing i have googled to see if there are any known issues ,, i wonder if you have any ideas ,, any help would be awesome .. ty - Earle

You can't measure analog video we refer to as acid test due to trigger, it doesn't have advance triggers as a proper bench scope would as you stated to complex of a signal for it rated specs. As far as digital signal square waves you need 10x the bandwidth analog and a lot more sample rate ADC. So watching your results was kind of expected for specs it claimed. The major issue is jitter and timing notice is pretty bad with this one, could be they are overclocking the ADC's? It good only for PASS, or No GO like most handheld of this price. I won't recommend for anyone that starting off, or using it instead of a bench scope at a a bench using as their main scope. One question is the channels isolated from each other. grounds on BNC's not shared, they claimed it was which would make it useful if it actually is? If you can measure the ground between the BNC GROUND? When they stated that it peaked my interest especially for the size it is. I actually considered buying one just to see if it does? If it does will be one of my main portable scopes that will be used as repair switch mode supplies and control units and it's small size throw in a bag and make it lighter as have to carry a lot of gear around the city and in a lot of cases have to take subway due to not practical and pain to drive in downtown area. The only other thing wish it had 5mV like my oversize truly isolated handheld Tektronix scope vertical sensitivity. The Owon does but channels not isolated so have to use a battery powered signal generator to offset, or bring differential probe. The scope section would be ok for HV so long channels are isolated from each other and you are using a appropriate resistor divider HV probe to the voltages are measuring, I measured 300v all the time and as high as 4kv on my Tektronix portable all the time and has the setting to accurate measure it with the appropriate HV probe. it is the main reason people buy these handhelds, especially us that repair power supplies. The multimeter won't trust for high current as lacking in protection area, when compared to a proper CAT rated Fluke multimeter. I had coworker manage to blow the flukes up even. For bench use the multimeter would be ok for low current, the multimeter section is better then my HDS3102m-n that costs way more like $425 more. The crosstalk may be another issue as no shields on this one, I wonder if that has something to do with the jitter I saw in your test, as seem to be worst when you enable the other channel? Good way to test is use one of the channels keep other channel on and put vertical to 10mV and see if that channel pickup the signal from channel you are using?

Can it measure 220V ac waveform?

😊😮🙏🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻

What about battery life time work?

When I tryed to firmware update, an error accured and never open osilascop again. plese help.

Looks like they removed the firmware from their website. Only the pdf is available :(

Hello, I'm new to electrical engineering as I'm just a second year university student. Is it possible to use this device to both generate AC signals and then display the same signals with the oscilloscope on the same device simultaneously?

7-zip my dude, dont use winrar or winzip

You are okay, but the instrument is very problematic. YOU CAN'T TRUST IT WHEN YOU TRY BOTH CHANNELS. Maybe they will be able to fix it in the Firmware sometime. Then I will consider it.
