One of the things that I like about this review is that even tho there was an "unboxing", you had already gone thru the process of understanding the instructions and reviewed how to get things working in advance. That really improves the quality of the review substantially over some others who don't actually spend the time and just muddle around while recording. Currently I am looking more for a 2 channel scope/meter but with a more standard Multimeter selector similar to the Mustool MDS9208 that you reviewed. Thanks for the great review.
Go to 34:52. There isn't much to complain about. The O-scope could be a bit better in its implementation. Banggood is like $90, so I expect EU folks and such with VAT are looking at 17-20% more. This might be decent if all you're doing it measuring simple sine waves other non-modulated signals.... All my uC and other circuits that I want to look at with a scope are generally modulated somehow so this thing is useless for anything above 500Khz, forget 1, 2, 5, 10Mhz, as it is advertised. For a modest amount more, one can get something that will actually perform as marketed. For less, one can get one easily equal to this. I like Terry's simple production work, however he rarely seems to want to anger his suppliers with a negative finding as that would probably reduce the amount of free equipments he gets for content. As someone looking for some of this equipment though, I WANT to know if something is actually worth my hard earned $$, not generic 'yeah its ok, not too bad', etc. I'll take the lazier, muddled recordings if they're will to call out equipment that is a rip-off and suggest something in the range that is actually competent over nice videos.
This is the best review I have seen on the 2C23T. You actually knew how to use it, a rarity compared to other reviewers who fall into the category of random button pushers who seem to never read the manual. Plus not comparing its readings with a high end thousands of dollars scope. I do have this unit and purchased it knowing it would have limitations. It will eventually be relegated to a secondary device to quickly see if there is a signal/reading. I mainly use it on music synthesizers to look at and inject audio level frequencies. Ultimately, a stop gap device while I save the money to purchase a half decent bench oscilloscope. I am still in two minds whether I should save money and get a two channel or spend a little more for the same model but with 4 channels. Thanks for the quality review.
@@shaunmorrissey7313 Let's be serious none of the low cost units are perfect. If you want accuracy, high bit count, stability and reliability then a respected brand name oscilloscope is what is needed. These low cost devices are just tools to do a limited range of measurements at ballpark accuracy. In some cases that is all one needs to determined if there is a voltage present and if within the devices capability if the voltage is changing over time. And it can always be used as a sacrificial device before connecting expensive test gear when operating in the "dark".
@@Alchemetica Come on, most of the people buying this are buying it primarily for its stated specs 10mhz, not as a DMM or Signal Generator. As I said in my OP that was deleted, for a measely $20-30 more one could get one of several decent handhelds that actually function at close to their marketed specs. Don't know about most people, but I don't have much call for measuring simple sine waves and such sans modulation. Terry seems unwilling to call junk, junk.
Actually not bad for the price. Two separate 10-bit ADCs, honest specs, clean design, can be quite appealing. Slightly low input sensitivity at 20mV/div. For simple diagnostics and for beginners, it should be fine.
Not honest, read @DerekWoolverton's comment below. I didn't notice that either.🤨 Fnirsi is a piece of garbage who lies about his specs. I can report this with 12 Fnrisi products in my inventory.❤ Of these, there are 4 oscilloscopes, and only one, the DPOX180H, can be used. The rest is garbage.🤣
@@juhaszpeter4796 If Fnirsi devices are such trash, I'm curious why you bought so many 😃 I know a few people who use these 'garbage' tools successfully for hobby/repair work and don’t really complain. Sure, some specs are exaggerated and they are overall maybe not the best choice, but despite that, they can still be used if you know its limitations. I always say to carefully check the specs and choose a device that fits your needs if you don't have a tons of money for the thing that does everything (perfect).
@@SlaVoy Because I'm too naive.😭 The problem is that it doesn't meet its own specification.😡 The radioactivity meter is because it produced good results in the videos. The first early pieces were still good, the rest were cheap, scrap parts, etc. The wall wire finder is because I needed one, it can be used, but I already drilled into the wire because of it... after that I bought a Noyafa or some brand of products. I bought the USB tester because it featured well in the videos, but also the bluetooth version 58. I am satisfied with that.👍 The wall moisture tester was necessary and it is good for being able to distinguish a dry wall from a wet one.❤️ I chose the SG-004a because it was cheaper and performed well in the tests, later I noticed errors, the ref voltage was not clear, it calibrates etc. But I like it, it's usable. I bought the 1013D because I wanted something better with a bigger display instead of Sigpeak's small one-channel handheld. but it was just a waste of money... less than a week later I bought a Micsig to1114 after that, it's a real scope and knows what it says it is. I bought Micsig about 50% more expensive than Fnirsi. I also bought DPOX180H instead of sigpeak, I already had two Owon HDS. I wanted another pocket instrument that was smaller than my two Owons. this is usable, but still not the real thing. I have to check back with Owon many times. I then bought the 2c53P, which I hoped would be good. After the DPOX180H, I expected better. Check out Kerry's video about it. it's a waste, the same as 1013d and 1014d... It's even worse, I don't dare to use it to measure voltages higher than 120V. I have a basis for comparison, and I have an idea of what it needs to know if the spec says this and that. But Fnirsi does not keep what it promises, only very rarely. A few pieces of equipment that I already had, it's true that it's very little, but it's more than nothing. Owon HDS272s, 2202 Owon PC scope 1022 if I remember correctly. Sigpeak I don't know which is single-channel. I lent it, it was lost. Micsig To1114, STO2002? the light blue with physical button and 200MHz. Rigol DHO924s Zoyi zt-703 Owon HDS120, although this is not the scope category. My problem with his scopes was that they didn't trigger properly, the Owon of the same category is better. I don't know how big the actual memory is, the Owon is always 4k or 8k which I set. Badly measured on occasion, as you can see in the video here. Wrong RMS calculation... I noticed that there were times when the wave did not look the same as on Owon and Zoyi. The two channels received the same wave, but one channel measured more than 20% more. etc. It receives a signal with the same frequency, on other scopes the two signals do not move rigidly relative to each other, but with fnirsi one signal moves relative to the other... And even more firmware bugs that will never be fixed. Those who praise it may be lying, unfortunately I know people like that. if it's bad for him, then it should be bad for others too. or I won't tell you that I made a bad deal, etc. I'm happy to admit if I'm wrong... or what is also possible, that person has no possibility of comparison and then does not know that Fnirisi is garbage.
@@SlaVoy The spec tends to exaggerate Fnirsi a lot, it's rare when Fnirsi is honest. Many things are omitted, reality is distorted. Me too chooses on the basis of specification, but that mod is worthless if the specification is not real, or is directly described as wrong way.
On a small device, It's important for readability that the available screen resolution is used for large font. Not only does the no-value-added bar graph take up space, it's impractical rounded shape takes up 3X the territory it should horizontally for each. Even worse, this happens on both sides, with no additional function provided by the second bar! All totaled, a full ONE HALF of the display is not used for text and icons in the multimeter mode, instead to make the display look trendy. Definitely designed for younger, more impressionable shoppers.
Watching the Vrms during the scope tests, regardless of whether it was being fed a sine wave, a square wave or triangle wave, it always displayed the same value for a 1v p-p. Seems fishy.
FNIRSI lies about all their products, at least the half-dozen I've seen reviews on. I'm just in the hobby end of things, but most of my signals are usually not simple since waves. With the conclusion stated in this video, I'm wondering if Terry is more interested in doing fair reviews or keeping the manf's who send him stuff happy.
Yes, it's fake.👍 This exactly reflects the philosophy of Fnirsi: "let's convince the customer to buy it, and if we have the planned income or there are many dissatisfied customers, let's release another piece of waste, which they will buy again..."🤮 Kerry didn't see the trick. It's hard to pay attention to everything at the same time, I also just checked my HDS120 because of your post, and I noticed that if the signal is asymmetrical, the multimeter part or the oscilloscope part is lying about the VRMS. The two do not show the same RMS.🧐 I tried with a square signal from 10% to 99%. Instead of or in addition to such Reviews, a video should be made where the device is tested point by point based on a plan, and only shows the errors and problematic parts. There are 1000+1 videos about such a device, many people should already be aware of their basic knowledge. Attention should be drawn to what mistakes they have. to the bugs. There are problems that you wouldn't even think of.i learn every days somthing news.😁 If kerry had made his video about the Fnirsi 2C53P sooner, I would have never bought that piece of junk.😭🤣😭
It looks like it may be estimating Vrms as Vp-p / (2 sqrt(2)), which is only valid for a sine wave. That's pretty lazy considering the scope has all the data needed to easily calculate Vrms.
In the "Confusing current mode" section, the zero readings were due to you cycling through into AC current mode, as shown on the display. When you cycled to DC current the reading was OK. I fall for it all the time as my Fluke 87 V defaults to AC current measurement.

yeah, great video, but i really didnt like the Multimeter especially the Capacitor tests (results)....not straight forward from the device point of view.
I tire of so many creators reviewing the same products especially when these reviews have replaced their previous videos about their projects, repairs and electronics education contributions.
Agreed. The Electrobananas channel did a more comphensive review a year ago,so this seems like duplication. But I guess if it is sent FOC by FNIRSI, there is an obligation to do a review 🤷♂️
