FNIRSI SG-003A Process Meter + DSO-TC2 Oscilloscope & Transistor Tester 

Dave's right here. As a newb electronics enthusiast I should probably go out and buy a $20,000 desk oscilloscope as my test rig. That'll get his seal of approval for sure

even in Europe the SG-003A does make sense ;) if you read a bit the manual. The scope you can get better for almoste the same price so it isn't with good enough specs.

That's the problem with the pro/rich, they forget what it was like to be a budget hobby guy. I use a DSO138 to do auto EFI work, which is fine because the highest trigger frequency I see is 6KHz max.

That would be a cool functionality to have.

If it were some pissing toy that didn't have a defined use case and/or had many potential applications, I might agree, but the use case for a process meter (you need to source/sink 4-20mA to zero-span an industrial process instrument) or a transistor tester (you need to determine actual hFE) is extremely niche even by electronics test equipment standards. The only appropriate question is "who needs that?". The actual industry techs are all using $2000+ Flukes and Metrahits, not because they're elitists but because those are the most cost-effective instrument. Nobody who actually needs a process meter can afford to dick around with a $50 aliexpress toy when potential downtime (the filthiest word in manufacturing) hangs in the balance, so who is this thing actually targeted at?

"...Fnirsi has some room for improvement when it comes to user interface..." HAH, HAH, HAH...D,Yah think? :)

Nope, tried it, nothing. UPDATE: Didn't work with my sony remotes, but my TV remote worked ok. It shows the bit waveform and hex code. So it's useful. Manual says NEC code only.

They call it a Process Calibrator on their Aliexpress store.

@@EEVblog Interesting, I guess that's different enough from ProcessMeter.

Yep, they are great and easy to use!

Did that, nothing happened. UPDATE: Didn't work with my sony remotes, but my TV remote worked ok. It shows the bit waveform and hex code. So it's useful. Manual says NEC code only.

@@EEVblog2 Sony, what do you expect? :D

Not below $10,000

example ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-z4-k5WXZnTI.html just got my unit yesterday, and Im very impressed for the price.. fascinating little gadget..

@@JAKOB1977 Thanks for sharing that video. It really puts Dave's nonsense to shame.

To test ir put in tester function (some need to push start and wait to fail) press a button in a remote control point to the tester and you have a code and a Graf.(don't work in all remote control)

Yep. Dave is clueless of the real world, so it doesn't know about TC1 or DSO138 or DSO150 or that most people don't have a wall of >$1000 single-function test gear.

Never heard of it.

Because Dave is clueless and just spams out these kinds of reviews.

That's exactly what this thing is... the usual software but a proper case. It can show ESR and all the other normal things .

Thanks. Oh your me. Hi me!

yes

Yeah, this is geared towards perhaps entry-level people who don't know too much. I do like the component tester, but I have several. What i like about this one, is the full-color display of the data. For me, color is a big deal. But even at the low price, I don't see this as anything that I'd want, ESPECIALLY with those horrible "connectors' and "adapter". Anyone who buys this and actually uses that adapter, I give it 1 day and it'll either snap the case or at a very minimum, bend the connector on the inside. The could have easily designed it to use real connectors.

Yes, he has his head up his arse sometimes...This vid was a waste of time. Totally half baked.

@@vincentwhite7693 Agree. Once you are used to the menu structure and did some basic settings the SG-003a is a breeze to work with and it is actually extremely accurate. It came pre-calibrated.! This review was very ill prepared and showed really nothing that this device can do, like programmable sweeps and modbus interface. Maybe watch a serious instruction video first Clive.

yep, kind a f3cep4lm when Dave started to nag and bltch about cycling thrue curve-screen and how convolute it was, when he already had concluded that the FN is obvious a function button. so its two button pushes.. FN + curve button (supprise) to toggle between screens. all the main features.. program/presets, Auto, signal conversions/convert etc etc.. is with FN and a button.. simply as the button destription says.. and it wil even lid up the button in different colors, sto highlight what feature you have rolling. same with the FN button that wil lid red, to show its active. with the price in mind, its a sexy little gadget and higher standard then I useally see from Fnirsi when it comes to build, that often looks like somethingone step from a DIY frankenstein project ..

JYE is not happy everyone stole their DSO designs and have been warning people of counterfeits for ages, so there is little chance they are open in any way. They even introduced an annoying counterfeit warning to their firmware.

@@SidneyCritic Check G1t Hu8

Nope. That's only audio frequency and really is a toy, not close to real instrument. Even older FNIRSI for $60, with its lot of bugs and shitty software looks much closer to a real usable instrument. This one is also much better than DSO shell and even has 10mV/div (5x better than $60 Fnirsi older one).

@@AndrewD-IT True but a $50 budget implies specific type of user; one who does not require more than simple signal tracing at 5v.

I do not know how you did it but you are FIRST!!!

Definitely write home to your mum about it.

@@RoderikvanReekum Wrong, not FIRST: it is FNIRST :P

ROFL yeah, they're having a difficult time HACKING better fonts. hehehehehe

LOL, I have no idea why everyone use the same shitty fonts, but you can immedaitely tell a CE product from that :D

Because that's the Latin alphabet font that's included with the Chinese font that they're using. This sort of thing even predates Unicode; you saw it in Big5-encoded fonts, too. Not totally sure why that's always been the case, but it's probably at least got something to do with the fact that the Chinese font is fixed width, but with a much more square aspect ratio that would be usual for a fixed-width Latin alphabet font, and I bet they used a serif version to help fill up horizontal width. These days, though, it's just "the way it's always been".

Agreed. I bought one to have in my tech go bag to go/no-go test hall effect speed sensors in Ag products. This was the cheapest battery powered thing I could find that does that and am very happy to have it. I am "pro" Avionics tech and only buy useful tools...

Blame Signal Path.. Its that backland that gives our aussie Dave an "inferiority tech-complex" and why he over and over, feels the need to step on and pfff on chinese budget tech. - "Its CN budget tech-dirt.. I only do it because they sent it to me and want me to ... and I will only glimse at this CN techdirt on my mailbag, and I dont even care if I dont understand 5% of how it works, as I will not put any effort into actually do my own due diligence and examine it a bit so I at least can present it in a transperant honest way to my viewers.. its CN techdirt it will undermine my social media influence tech renomme, if I roll in the dirt with CN budget tech and put anykind of effort into it".- but yeah, its a hard days night when he goes on these nagging rants, when its all down to himself. "its so convoluted to change the curve-screen" 6:58 with this "menu" i have to go to' and so many button presses. when in fact, all he had to do was two button-pushes..- function-button aka "FN & curve button" to toogle from curve-screen. (supprise) all the features, are with the FN button and then the corresponding button that clearly says on it what it does - and the buttons will even lid up in different colors to highlight what mode your in. // anyway, good news both Shahriar from Signal Path and also my main man Ben from Applied Science is on board, and will gladly take a talk with Dave, so we can get that inferiority tech-complex sorted..

@@JAKOB1977 - That explains so much. Thanks a ton for the perspective and info. I see clearer now.

Yeah, the big names (read EXPENSIVE) aren't always necessary. I have several multi-meters, including a Fluke. Of course, I've compared accuracy with all my meters against the Fluke and all of them are bang on (or at least within a tiny margin of difference). In fact, I have some meters that I like a lot better than this Fluke. Needless to say, the Fluke was expensive and in hindsight, I should have saved my money, because it's not THAT MUCH more accurate than others I have. My main Lab meter is in fact a Siglent SDM3045X and I can say, this is my favorite meter of all that I have. However, it's very NOT PORTABLE. LOL

This is an extract from a mailbag video where I literally take it out of the box and play with it. That's the entire point.

That video you're referring to might be one by Andreas Spiess. _He has_ such a video, at least, whether or not it's the one you mean :) Andreas' video is years old now, I think, but he republished it a few weeks ago, so it should be easy to find near the top of his videos list 👍 (I'm never sure if it's safe to include links in comments...) That Zener diode inaccuracy towards the end of Dave's video surprised me. I thought these testers were generally decently accurate 🤔 Maybe this one needed calibration? Or did they cheap out on some parts (like using a lower-accuracy TL431/other Vref)? I don't have time to check Dave's high-res photos to see if stuff like that is visible, sadly. I'm also far from an expert on this topic :) (though I have read through a lot of the original documentation and schematics)

@@AndrewGillard Indeed, that's the one. Thank you for that info, here. The video is "#290 How do transistor testers work" I'm frankly pretty amazed these things are as accurate as they seem to be... and zeners' Vr varies dramatically with current. But, yeah, I'm betting the cheap devices use low-tolerance parts. There are so many different types of components, even "regular" diodes with low reverse breakdown voltages, but they wouldn't be called proper zeners, so it really boggles my mind how this tool can figure out the difference between things like those two without potentially damaging one. *Very* low measurement currents, I'm guessing, which would surely affect readings like diode voltages. I always just thought of the tool as a component-identifier, as opposed to a component qualifier. I suppose a configurable second-step test could be useful: "This looks like a zener, around 20V, Do you want to try a higher current to get a more accurate reading?"

chill out

@@jaro6985 Yes Massa

my guess is Chinese people name chinese companies, and likely do it according to their own language and not what it may sound in fx my native tongue danish, or English for that matter. the balls on these chinese people to name their name according to their own language.

Surely it's not REALLY so difficult to work out? It's a simple scope added onto a Transistor Tester, not the other way around.
