Thanks for another well detailed review. Can I please make one suggestion for future videos. When testing the scopes bandwidth are you able to also test it by using a square wave as well as your usual sine wave tests. Most scopes will be able to handle a sine wave at its rated bandwidth. But the real test is using a square wave. This is also why most signal/function generators have less bandwidth for a square wave but a higher one for sine waves. Thanks Hugo. I really appreciate your effort in making and editing these videos.
Yes you need typically 10 times the bandwidth plus for square waves. I would like to see a version of this with at least 50 mhz bandwidth and at least two 500msps ADC’s interleave and a proper component tester with ESR and LCR capabilities but wishful thinking. I would pay more even if $150 more for that as would save a few bench space and be a very useful tool to being one of the most tools on the bench and pretty sure it would sell out if made one even at the higher price. A proper component tester would make this a game changer and don’t understand why these Chinese companies have not done one yet? Look at how well the small cheap component testers with ESR well, pretty much most the bigger RUclips techs use them for repair daily as cheap and gets the job done while taking basically no bench space. Imagine one in one of these oscilloscope multimeter it literally be a game changer. Yes I fully understand why Fluke and other big manufacturers haven’t as safety becomes a issue as those meter are targeted for also the industry field where you deal with transients and high currents it for bench techs and engineers that do repairs, designing a LCR/ESR meter is a must and have a decent multimeter with oscilloscope and function generator and component tester with LCR/ESR capabilities would be gold.
@@thetechgenie7374 It would be perfect if they could combine all your suggestions into the scope/multimeter. A proper component tester with ESR and LCR combined into a this scope/meter would be a winner. Plus Like you mentioned, if it had 50Mhz bandwidth I would get one straight away.
Hi, nice to "see" you again. I will try to give more time to other sine waves, like the square wave. The square wave is really harder to have it properly displayed, thats true. Most of the times is just I forget... Thanks for watching!

Why is a square wave 'harder'? Because they contain higher frequencies. How do you objectively measure its ability to measure higher frequencies? By putting pure sine waves through it. Higher frequency sine waves will give you the information you're asking for. If you think they won't, you need to rethink your question and what it really means.
Seems like a pretty decent package. Would be interesting if they did a similar multimeter unit combined with the process calibration functions of the SG-004A. Thanks for the thorough review. 👍👍
Parabéns excelente canal, desde já muito tempo que vejo canais com este tipo de temática, e foi hoje a primeira vez que o seu canal apareceu nas recomendações mesmo tendo pesquizado alguns dos equipamentos que já fez review, agora já não me escapa, abraço.
Olá Eduardo, obrigado pelo simpático comentário. Eu tenho ainda o mesmo canal com os videos em Português, mas era demasiado trabalho e tive de me deixar só por fazer em Inglês... é mais universal. Obrigado por assistires e espero "ver-te" por aqui.
Hi, it is very similiar to the ZT702S, I think is aimed exactly to the same target audience. In terms of specs and everything, they're pretty much identical. Thanks for watching.
I am disappointed with the second channel jitter when both channels run. Not good for example for audio channel testing. Perhaps in the audio frequency range this error would not occur.....
They have already uploaded an update but they don't mention fixing this problem. Maybe they pushed the device in haste. If they fix this, it will be very good device.
Hi, as mentioned before, they have already an update, I'll do a video with this update and then see if it improves. Overall is not a bad device, but does have it's quirks. Thanks for watching.
More than one bug to be fixed. It's a universal feature of all software development today that testing is not done to any satisfactory standard. I was testing manager for many years for a multinational insurance company and testing was done both to prove expected outcomes AND regression testing to make sure new software didn't f*ck production results. Regression testing found MANY faulty upgrade submissions.
Hi, you probably right. Some better testing will prevent a lot of issues. The ones I found are not terrible, but saw in other devices/manufacturers more serious cases. Thanks for watching and your comment!
@@TechCornerTVhi, seeing your review of ZT703 seems its as good. ZT703 price is just a bit higher, only its looks and its display design seems better. What would you recommend? ❤thanks again.
Not the best scope but will be a great tool for a tester to save on space and do many measurements as you get a multimeter ( resistance capacitance voltage and current) Basic Dual Ch Scope 10Mhz and Signal Gen ( sine square saw half wave full wave noise and dc) all in one package. Only thing I found missing was that it doesnt show that it is charging or fully charged when turned off on charge.
Hi, well, I have to confess that I might be wrong, nowadays even with glasses, I have some difficulty seeing small things and I might have confused. Need to update my glasses. Will be more careful next time. Thanks for watching.
1. Can it record longer "rolling" waveforms, or only what you see on the screen? 2. Is there a way to export files to the PC computer, and what's the format/resolution of the pictures?
Hi, it can save pictures, not waveforms, so 1) is a no. You can connect to the PC and download the pictures, they are saved in BMP format. Thanks for watching.
Hi, I think they are mostly identical, maybe this one has some more functions. I'm still waiting for the new ZT703S that should arrive soon, maybe that one can really make a difference. Thanks for watching.
Thanks for this video :-) I just received this meter by mail. Does anyone know what the max voltage is that I can feed into the oscilloscope? I want to check a stepper driver with 12 volts output.
Hi, there is always someone that this can be a good solution, totally get what you say. In terms of multimeter, all measurements I made are within the specs of the device. Thanks for watching and your comment!
Hi there, it was added to my todo list. Not sure when will be able to do it, but it's there and will make one. All time favorites or by category, ie. ex. oscilloscopes (all) or bench oscilloscopes and portable, all multimeters or bench multimeters, etc. Thanks for watching.
I appreciate your review. I was interested in this model originally, and it has a great looking display + features, but the 20mV vertical sensitivity of the oscilloscope is a real turn off. Other budget models have 10mV or better. :(
Hi Marty, yeah, I don't know why they did that, most of the oscilloscopes have a 10mV minimum. Again, I prefer 20mV accurate and serious, that 10mV announced that after will now work properly on that range. Thanks for watching.
@cristian7477 Hi, can read spaninsh, but writting is a diffreent story 😁 I'm trying to get time for that. Will compare smaller oscilloscopes and those portables on a showdown. Receive two new ones this week and have to do a video on them first. Thanks for watching.
@EletronicaeTecnologia Olá Daniel, fiquei muito impressionado com o aparelho, existe ali alguns bugs quando usas os dois canais, mas no geral, muito bom. Fico a aguardar o teu vídeo e obrigado pela visualização e comentário 💪
O melhor osciloscópio que a firnisi construiu, foi o 1c15. Pega o sinal em forma de pacote, tensões fidedignas, sinal de referência, botões de atalho e por aí vai. Obs: ela poderia lançar o 1c15 canal duplo, com a mesma tecnologia, ou sja dois canais. 👏 Pelo vídeo
Olá Marcelo, peço desculpa por esta resposta atrasada, mas não está fácil responder a todos 😁 eu fiz uma review ao 1C15+ e fiquei muito bem impressionado com ele. Eu gostei muito mesmo do DPOX180H, acho que eles se esforçaram mesmo muito nesse, mas não retira o crédito do que disseste e também penso que o 1C15+ é um bom osciloscópio par ao preço. Obrigado por assistires e comentares.
Hi, you can, but you have to observe all the requirements needed to analyze high voltage signals, starting with the limit of the max voltage allowed in the probes, but 120v shouldn't be an issue. Thanks for watching.
Hello friend what is your opinion to choose best accuracy handheld oscilloscope fnirsi 2c23t or zoyi zt703s ? Which are more better with more function ? I need only best accurate handheld oscilloscope function only
Hi, never tested in that scenario, but those inverters have frequencies over 10Mhz?? AC in landline use 50/60Hz. Over 10Mhz, that's a very high frequency. Thanks for watching.
How's the battery life after owning it a bit? My fluke needs a new battery every 6 months or so. I know this won't even be close, but I'd rather not lug a battery around with me everywhere I go in the chance it'll be dead at the job.
Hi, I have several multimeters and not always use this one, but for my experience you can have it like always ON easily for 4 to 5 hours. Thanks for watching.
Olá, peço desculpa pelo atraso na resposta, espero ainda poder ajudar, mas tenho andado algo ausente do canal. Para um orçamento desse valo, eu recomendaria Hanmatek SDS1102 ou qualquer coisa assim, a ultima vez que vi, estava no AliExpress ( www.techcorner.tv/aliexoress ) por 150€. É baseado no Owon com o mesmo modelo, para esse preço é o melhor que se consegue. A CDEK tem o mesmo modelo em preto, gosto bastante, procura por SDS1102, mas sem ser Owon que é mais caro. O preço é idêntico. Obrigado por assistires.
Hi, I have one somewhere but didn't found it and was not able to test temp because of it, so, you're right. It's a cheap thing that can be included. Thanks for watching.
Good review, but... You got a free device, you got affiliated links, and you say you are not sponsored? What is your definition of a sponsorship for a RUclips channel with 6.73K subscribers?
Hi, a free device is not sponsor, they have interest in the review to publicize the device, but this video is sponsored by PCBWay, the channel sponsor and those does contribute monetary for the channel. When I say is not sponsored and I didn't receive any money means, this is not a paid review like there is much out there, that's all. Thanks for watching.
@@TechCornerTV Yes, I know what True RMS is. Does it list any specs on it's RMS performance? I'm looking for something that can calculate True RMS on very much non-sinusoidal audio waveforms above 1khz.

I just found your channel. Great video and I subscribed. I'm from Portugal also and I would like to ask a question about pcbway: If I buy from pcbway, will I have do deal with customs? Or, like other big stores outside of the EU, does pcbway charge vat in advance and therefore I won't have to deal with customs? Thanks. Cheers!
Hi Bruno, welcome aboard!

But please inform yourself better, this is my experience. Thanks for watching and I hope to see you around 😁
thanks alot for the reviow , i got one ^^ , can we calibrate the probe ? I made low frequency square wave, trying to adjusted with the trimmer but nothing happening
Hi, 200V require the 10X attenuation. If you're using the test probes already with the 10X mode on, you probable should be able to do it. Thanks for watching.

Hi, DSO3D12 is a very nice device and it is in most specs superior to this one. The oscilloscope is 100Mhz and you have also more functions like cursors, XY mode and a few others. This one is more comparable to the Zoyi ZT702S. Thanks for watching.
Hi Josh, personally I'm not familiar with automotive diagnosis, but for the comments I read from other viewers, I think you'll be alright with this device. thanks for watching.
@@TechCornerTV thanks for the reply, I unfortunately bought a hanmatek ho52 before seeing this review and the multimeter on that one is either crap or my mine is faulty from factory…
Hi Mohammed, LCR meters are pricy and for some reason I didn't review any yet. The only one that I can mention to have passed here in the channel is the ruclips.net/video/2YmKa-0DWEs/видео.html (Shannon tweezers) a very good product, but not sure if it what you're looking for. Thanks for watching.
Hi, yes, on taobao you have really good prices, I have an account there, but is impossible to buy there and have it shipped to Europe, and is also everything in chinese. Thanks for watching.
it's pretty similar to OWON multimeters... same key pad distribution and function... Chinese industries makes a "standard" main board and just makeup it with minor changes on plastic shell presentation... Some menu differences but essentially same product.
Hi Claudio, sorry the late reply, trying to keep up with the comments, not easy. I've been wanting to test the 200Mhz Owon portable one for quite some time, but it is expensive and right now I have other priorities.

good thing ,, stupid testing no joke , put it in a real use stab it in to outlet and what not , question , what about those scales , not moving ,gimmick ?
XY display mode Yes or No on this China thing... I see BNC connectors are to deep, not proper insulation for CAT ratings they claimed, 2 much power consumption like 2-3 hours useful time, temperate probe is not accurate at all, resolution is 2 low and I see blurred pictures, standard pack with only one (1) probe etc, etc, just a kids toy, if you use 2 channels at once... you'll be disappointed, only useable for audio ranges
Hi, sorry the late reply, trying to keep up with the comments, not easy. It doen't have XY mode, thanks for sharing, I really appreciate the time and thanks also for watching.
If they put a proper component tester with ESR capabilities and maybe even LCR it be a tool that would use all the time. Even if they increase the price $50 to $100 pretty sure they would sell quite a bit more as I would buy one. It one thing that multimeters don’t have that most pretty sure most of us would like to have. A proper component tester. One of these companies needs to do one already? It would save us bench space. I get why Fluke and other known manufacturers haven’t as safety becomes a issue, but for an electronic technician or engineer working with low voltage and current projects on bench would be valuable and not an issue.
I agree with you. If they can combine a proper component tester together with an LCR meter into this scope/multimeter I would buy it straight away. It would help with my limited bench space. The only issue I have with this scope is that the bandwidth of 10Mhz is too low. If it was above 50Mhz it would be a winner.
Hi, there is a very few devices/multimeters that have the LCR function in it, don't know why. Probably the mecanics to allow the measurement of inductors increase the price a lot. The LCR devices are always a bit pricy. Thanks for watching.
Hello, not with this one, is a 10Mhz oscilloscope. Take a look in the DPOX180H, is a very nice FNIRSI portable oscilloscope that goes up to 180Mhz (if I'm not wrong). Thanks for watching.
@@TechCornerTV oh no i bought thie device for mobile repairing and i asked from seller before purchasing either this device able to measure 50MHz or not. He sent me data sheet which i was not familiar. I thought Data rate 50MHz is the measuring range. 😔😔
Hi, it depends of your need, if you need an multimeter, DPOX180H will not work, on the other hand, if you need higher bandwidth support, you need to go to something like DPOX180H or DSO2512G, DSO3D12, etc. The good thing is always having options acording your needs. Thanks for watching.
Nice product presentation! Can you confirm if oscilloscope channels are isolated? Grounds are not common? To measure signals with different references. Thanks!
Not impressed at all: A 3 V signal from its internal Waveform generator read as 3.21 Vpp.... Really ? For the rest, in oscilloscope mode, differences in frequencies of two signal of the same frequencies.... Really ? Fnirsi has deivered much better tools lately. I'll avoid this one !
I seem to remember see on a budget selling website a multimeter with a good Thermal camera about £100.00 that is much cheaper that other thermal camera's of the same pixel density... this misses this option :)

@cristian7477 Hi, can read spaninsh, but writting is a diffreent story 😁 I'm trying to get time for that. Will compare smaller oscilloscopes and those portables on a showdown. Receive two new ones this week and have to do a video on them first. Thanks for watching.
@EletronicaeTecnologia Olá Daniel, fiquei muito impressionado com o aparelho, existe ali alguns bugs quando usas os dois canais, mas no geral, muito bom. Fico a aguardar o teu vídeo e obrigado pela visualização e comentário 💪
Can I change the voltage output of the function generator to the millivolt range like 0.0025 volts with 1khz frequency?
Hi, no, it's not possible. Thanks for watching.
O melhor osciloscópio que a firnisi construiu, foi o 1c15. Pega o sinal em forma de pacote, tensões fidedignas, sinal de referência, botões de atalho e por aí vai. Obs: ela poderia lançar o 1c15 canal duplo, com a mesma tecnologia, ou sja dois canais. 👏 Pelo vídeo
Olá Marcelo, peço desculpa por esta resposta atrasada, mas não está fácil responder a todos 😁 eu fiz uma review ao 1C15+ e fiquei muito bem impressionado com ele. Eu gostei muito mesmo do DPOX180H, acho que eles se esforçaram mesmo muito nesse, mas não retira o crédito do que disseste e também penso que o 1C15+ é um bom osciloscópio par ao preço. Obrigado por assistires e comentares.
Can you use this to look at the ac voltage on a 120 volt outlet with the oscilloscope mode/probes ?
Hi, you can, but you have to observe all the requirements needed to analyze high voltage signals, starting with the limit of the max voltage allowed in the probes, but 120v shouldn't be an issue. Thanks for watching.
Hello friend what is your opinion to choose best accuracy handheld oscilloscope fnirsi 2c23t or zoyi zt703s ? Which are more better with more function ? I need only best accurate handheld oscilloscope function only
Next up: integration of this device, their component tester and process calibrator and you'll be ready for on the go testing.
Hi, the swiss nife of the electronics lab... 😁 it will be cool if they manage to do it, but don't see it happening. Thanks for watching!
What's the long time for battery working ? because I thinking about that and other tablet oscilloscope
Is the 10Mhz bandwidth sufficient for measuring mosfets of high frequency power inverters ?
Hi, never tested in that scenario, but those inverters have frequencies over 10Mhz?? AC in landline use 50/60Hz. Over 10Mhz, that's a very high frequency. Thanks for watching.
Does it have an XY mode?
Hello, this one doesn't have X-Y mode. Thanks for watching.
Once again, an affordable tool for hobbyists by fnirsi! Thanks for your review and testing this ne device!
Hi Markus, my pleasure! Thanks for watching.
Благодаря за труда.
How's the battery life after owning it a bit? My fluke needs a new battery every 6 months or so. I know this won't even be close, but I'd rather not lug a battery around with me everywhere I go in the chance it'll be dead at the job.
Hi, I have several multimeters and not always use this one, but for my experience you can have it like always ON easily for 4 to 5 hours. Thanks for watching.

Podes me recomendar um bom osciloscópio 2 canais até 150€?
Olá, peço desculpa pelo atraso na resposta, espero ainda poder ajudar, mas tenho andado algo ausente do canal. Para um orçamento desse valo, eu recomendaria Hanmatek SDS1102 ou qualquer coisa assim, a ultima vez que vi, estava no AliExpress ( www.techcorner.tv/aliexoress ) por 150€. É baseado no Owon com o mesmo modelo, para esse preço é o melhor que se consegue. A CDEK tem o mesmo modelo em preto, gosto bastante, procura por SDS1102, mas sem ser Owon que é mais caro. O preço é idêntico. Obrigado por assistires.
great job and good price
Hi Alvaro, I agree with you, well on the price part! The "great job" part, I will just thank you for your kind words and for watching the video.
I miss a temperature probe in the package as Zoyi ZT702S does have
Hi, I have one somewhere but didn't found it and was not able to test temp because of it, so, you're right. It's a cheap thing that can be included. Thanks for watching.

Good review, but... You got a free device, you got affiliated links, and you say you are not sponsored? What is your definition of a sponsorship for a RUclips channel with 6.73K subscribers?
Hi, a free device is not sponsor, they have interest in the review to publicize the device, but this video is sponsored by PCBWay, the channel sponsor and those does contribute monetary for the channel. When I say is not sponsored and I didn't receive any money means, this is not a paid review like there is much out there, that's all. Thanks for watching.

Does this scope calculate True RMS?
Hi, true rms is used on the voltage measuring on AC mode of the voltmeter, and yes it does have True RMS measuring. Thanks for watching.
@@TechCornerTV Yes, I know what True RMS is. Does it list any specs on it's RMS performance? I'm looking for something that can calculate True RMS on very much non-sinusoidal audio waveforms above 1khz.

Is it possible to connect an amp clamp to this portable oscilloscope
Hi, sorry the late reply, trying to keep up with the comments, not easy. I think it is, I have here a few to test for oscilloscope and multimeter. When I have the time I will do a video with it. Thanks for watching.
I can't decide whether to buy the zeeweii dso3d12 or fnirsi 2c23 who is better?
Hi, I can't tell you what you should do, my videos give information so it will help on you decision, but I can't choose for you. FNIRSI did a great job with this device, I like it very much, but Zeeweii is also a fine product. It comes out out of what form factor you like more, the bw that you'll need. Thanks for watching.

I just found your channel. Great video and I subscribed. I'm from Portugal also and I would like to ask a question about pcbway: If I buy from pcbway, will I have do deal with customs? Or, like other big stores outside of the EU, does pcbway charge vat in advance and therefore I won't have to deal with customs? Thanks. Cheers!
Hi Bruno, welcome aboard! It was a long time the last time I had to pay for PCB's, but when I'm ordering, I always select a shipping method that has IOSS, that allow to declare the taxes on the source and not have to wait for customs release.

thanks alot for the reviow , i got one ^^ , can we calibrate the probe ?
I made low frequency square wave, trying to adjusted with the trimmer but nothing happening
If I am measuring a 200 volt HT line in meter mode, can I switch straight to scope mode to check the ripple wave form on it?
Hi, 200V require the 10X attenuation. If you're using the test probes already with the 10X mode on, you probable should be able to do it. Thanks for watching.
Hey dear I'm very interested to order the oscilloscope digital multimeter I'm living in Kinshasa Congo democratic

is this better than zeeweii dso3d12?
Hi, DSO3D12 is a very nice device and it is in most specs superior to this one. The oscilloscope is 100Mhz and you have also more functions like cursors, XY mode and a few others. This one is more comparable to the Zoyi ZT702S. Thanks for watching.
Is this worth buying for automotive diagnosis
Hi Josh, personally I'm not familiar with automotive diagnosis, but for the comments I read from other viewers, I think you'll be alright with this device. thanks for watching.

Suggest me some best LCR METER
Hi Mohammed, LCR meters are pricy and for some reason I didn't review any yet. The only one that I can mention to have passed here in the channel is the ruclips.net/video/2YmKa-0DWEs/видео.html (Shannon tweezers) a very good product, but not sure if it what you're looking for. Thanks for watching.
@@TechCornerTV thank you i will check it out
It's $50 on taobao. I'm buying one
Hi, yes, on taobao you have really good prices, I have an account there, but is impossible to buy there and have it shipped to Europe, and is also everything in chinese. Thanks for watching.
it's pretty similar to OWON multimeters... same key pad distribution and function... Chinese industries makes a "standard" main board and just makeup it with minor changes on plastic shell presentation... Some menu differences but essentially same product.
Hi Claudio, sorry the late reply, trying to keep up with the comments, not easy. I've been wanting to test the 200Mhz Owon portable one for quite some time, but it is expensive and right now I have other priorities. But I think you're right, they copy each other, but since everything nowadays come from China, who else will they copy 😁 Thanks for watching.

good thing ,, stupid testing no joke , put it in a real use stab it in to outlet and what not , question , what about those scales , not moving ,gimmick ?
XY display mode Yes or No on this China thing...
I see BNC connectors are to deep, not proper insulation for CAT ratings they claimed, 2 much power consumption like 2-3 hours useful time, temperate probe is not accurate at all, resolution is 2 low and I see blurred pictures, standard pack with only one (1) probe etc, etc, just a kids toy, if you use 2 channels at once... you'll be disappointed, only useable for audio ranges
Hi, sorry the late reply, trying to keep up with the comments, not easy. It doen't have XY mode, thanks for sharing, I really appreciate the time and thanks also for watching.
If they put a proper component tester with ESR capabilities and maybe even LCR it be a tool that would use all the time. Even if they increase the price $50 to $100 pretty sure they would sell quite a bit more as I would buy one. It one thing that multimeters don’t have that most pretty sure most of us would like to have. A proper component tester. One of these companies needs to do one already? It would save us bench space.
I get why Fluke and other known manufacturers haven’t as safety becomes a issue, but for an electronic technician or engineer working with low voltage and current projects on bench would be valuable and not an issue.
I agree with you. If they can combine a proper component tester together with an LCR meter into this scope/multimeter I would buy it straight away. It would help with my limited bench space. The only issue I have with this scope is that the bandwidth of 10Mhz is too low. If it was above 50Mhz it would be a winner.
@@khuongathebounga4141 a 50 MHz bandwidth with at least a proper adc 500msps would be the sweet spot.
Hi, there is a very few devices/multimeters that have the LCR function in it, don't know why. Probably the mecanics to allow the measurement of inductors increase the price a lot. The LCR devices are always a bit pricy. Thanks for watching.
Hello dear, we can't measure 50MHz or 40MHz witn this meter?
Any answer please?
Hello, not with this one, is a 10Mhz oscilloscope. Take a look in the DPOX180H, is a very nice FNIRSI portable oscilloscope that goes up to 180Mhz (if I'm not wrong). Thanks for watching.
@@TechCornerTV oh no i bought thie device for mobile repairing and i asked from seller before purchasing either this device able to measure 50MHz or not. He sent me data sheet which i was not familiar. I thought Data rate 50MHz is the measuring range. 😔😔
It’s better other opciones like dsog dpox,dso3 zweii but this isn’t necessary it’s very bad
Hi, it depends of your need, if you need an multimeter, DPOX180H will not work, on the other hand, if you need higher bandwidth support, you need to go to something like DPOX180H or DSO2512G, DSO3D12, etc. The good thing is always having options acording your needs. Thanks for watching.
Signal was 6 MHz and cheap device said 7 MHz, the tester guy said "it is within specs". Totally useless review and useless device.
Thanks for watching!
Nice product presentation! Can you confirm if oscilloscope channels are isolated? Grounds are not common? To measure signals with different references. Thanks!
Hi, I went to check and yes they are common, ch1, ch2 and signal output, all use same ground. Thanks for watching.
Not impressed at all: A 3 V signal from its internal Waveform generator read as 3.21 Vpp.... Really ? For the rest, in oscilloscope mode, differences in frequencies of two signal of the same frequencies.... Really ? Fnirsi has deivered much better tools lately. I'll avoid this one !
Hi, I get your point, thanks for watching.
In my case accuracy not really an issue. Go or no go is all I want.... At that price I want one NOW for my tool box!
This much error is ok for this price range
Probably utilizes 3V3 logic which is then capacitor coupled leading to 3V3p-p.
