Thanks for going through all the functions and settings. This is my very first oscilloscope and I know almost nothing about how to use one. :)

[@ActualAkshay]

Great videos! Please never stop making them ❤

[@holzhauser3532]

was looking for a manual for this device-this is one of the best to be found!! thank you!

[@cpcnw]

"It's FUN and that's what electronics is all about" - well said. Too many consumers of content. We need makers :)

[@PunakiviAddikti]

Big thanks to the quick user's guide. Now that I know what I'm doing I can properly use the scope. Can't afford a real big oscilloscope so this will do just fine.

[@empresador]

Thank you! I learnt how to use mine watching your video :D .

[@victor7530]

Thanks for the information. I now understand better how to use the oscilloscope.

[@20thcenturyboy85]

Thanks so much for this explanation. Great video.

[@carlos2004]

just got mine yesterday and just playing around with it for now. i got the fully assembled kit (except the case) and, as expected, worked right out of the box. also, pretty cool that is 9v which means we can just throw a 9v battery on it and make fully portable. i can easily recommend this to anyone doing electronic projects as a hobby. for the price, this should be the next measuring tool after a decent multimeter. my biggest gripe about is that the trigger starts at the middle point and basically the first half of the measurement is garbage and leaves the second half of the graph with only limited space for the signal you actually want to capture. for example, when sending the IR codes, they have to pretty small in order to fit the whole sequence, if i try to make them wider, only about half of the full sequence will actually fit. anything longer than about 8 bits and you won't be able to read it due to the trigger starting in the middle. and lastly, in the video he mentions he could not get the save/recall functions to work. they work fine, but is the adj+sec/adj+trigg that calls them, not the ok+sec/trigg. so no, don't expect a fully featured scope, but this is definitely useful for simpler projects or troubleshooting them.

[@markrhine5809]

I was thinking of purchasing on of these to test the foil side of capacitors, this video was well viewing I wll watch this again... thank you for posting this...):

[@superdau]

For the price this oscilloscope is unbeatable, which is why I bought one a few days ago on banggood. Of course you must not expect any accuracy (if you do, I guess you don't have enough experience yet). But it is a 100% suited for simple failure checks in devices. I'm taking part in a "repair cafe" (that's where people repair things for other people) and we don't have the money to buy measuring equipment (since we do the repairs as volunteers for free). I for sure won't take my own clunky analog scope there with me. But this thing will be perfect for measuring if power supply voltages are stable or a certain signal is at a certain point for example. I will also mod it to be battery operated (I already have a 800mAh Li-ion cell and a charge-module here from a previous project; waiting for the mini step-up converter). After that I don't have to worry about measuring anywhere I want in a circuit, even those where the low voltage is not isolated from the mains (I know that can be dangerous; but carrying an isolation transformer around all the time isn't an option either).

[@electroLuke]

Yes, I totally agree with your insight, and I am also willing to do the same mod and a tutorial beside it to share with others. I just need to find some spare time for that.

[@mrfurball]

I'm pretty sure in the 1960's NASA were using inferior Scopes when working on the moonlanding project , and as we all know , even with unreliable Scopes compared to today's standards they still managed to land astronauts on a film set in Arizona, shame time traveler's didn't allow NASA to use iPhones cause instead of the moon landing ,NASA would of landed on a Mars film set instead with the power of apple's crusty products.

[@enigma7070]

superdau - Are you saying that because you will be using battery power, you don't need an isolation transformer since you won't be sharing a ground reference with the circuit under test?

[@coriscotupi]

@@enigma7070 Not being directly connected to mains removes the danger of accidentally connecting the probe ground wire (which in most scopes is directly connected to the mains ground and has the same potential as the neutral mains line) to a live mains terminal shorting out the mains through the probe. With this particular scope, I do doubt that the power supply is not fully isolated from mains, i.e., the probe negative/ground is very likely NOT connected to mains ground or neutral, making it safe to probe at will (within the scope's voltage limitations of course). But precautions must be taken first, to ascertain if this is in fact the case.

[@fongy200]

I convert vintage Valve / Tube Radios into Guitar Amps, my Oscilloscope broke and because their essential to my process i needed one. It must not break the bank and it must be pretty mobile as i have a couple of benches in different rooms. If your a hobbyist and your doing electronic projects these are a must. Test equipment can be expensive so this was ideal. It's not bad for £22. The 2 channel model is only £44 so i may invest in one of those if i cannot find a replacement CRT for my main one.

[@roguepaul]

I have a newer version. I am not getting the same inaccuracy problems. learn to measure freq and amplitude manually using the grid and div you have selected to verify. If you have a full size scope available your not gonna use this one. But this one is perfect for lower frequency projects if you can't afford a big Oscope. Any eyes on what your circuit is doing is a good thing.

[@electroLuke]

well said

[@SunflowerandFriends]

What model is the newer version?

[@PT63]

@@SunflowerandFriends In principle it's not that old. There are three parts that were updated regulary and JYE has a good documentation about this on their homepage. Video: - Main Board: ver. E - Analog Board: ver. E - Firmware: 061 Latest: - Main Board: ver. E2 (probably because of display with new controller) - Analog Board: ver. F - Firmware: 120 The difference between the Analog Board version E and F is not that much. Only a protection resistor was added. But the Firmware was improved a lot and should be updated. Even this is possible for this low-cost device.

[@keithking1985]

@@PT63 I just got one the other day and still have to build it to you think mine wil I have the updated firmware??????

[@paulhartman5683]

Thank you very much!

[@JerryEricsson]

Those stand offs around the button should be screwed to the board that holds the button, this will align the button with the hole for you. I built mine a year ago and never could get it working. One day, I was describing the problem on a forum when it dawned on me, the problem had to be in the rotary encoder. So I ordered in 10 of them, and mounted a new one. I had a difficult time getting the old one off that board so soldered it directly to the main board, it worked fine and suddenly I had a working mini oscilloscope. This after buying one of the larger models of scope kit, which I built up and have working as well, so now I can hook two scopes to two different places on the device I am working and have two separate reads of the problem.

[@RalphWLundvall]

Jerry, where did you source your 10 rotary encoders? I need to replace mine.

[@themadatheist1976]

Shame they didn't have these kits when I went to tech school. We had the analog and digital multimeter kits back in 95-97.

[@capth00k]

Just bought one of the kits that you have to assemble -- it was $25 with shipping, so maybe I overpaid a bit but this still seems like a really good deal. I do wish that it had a battery compartment for the 9v, but I'll work something out. Did you add a battery to yours? what is the battery consumption like?? I'm thinking of perhaps going with a rechargeable lithium cell (flat) which wouldn't add a lot of bulk to the unit.

[@JSG550]

would this be good for monitoring an amplified EEG signal?

[@juannordh1500]

Perfecto in my toolbox.

[@garyr7027]

Bought this same model and it worked the first time. The only problem I'm having with it is V/DIV button wants to hangup. It's soldered fully flat on the circut board, but for some reason the front cover won't let it pop back up like it should. Probably gonna have to modify that cover a bit... i think it's slightly warped.

[@hann_ottostore2220]

Can i use it for testing and displaying the signal which the High is 12V and the Low is 0 V ? Such as, one of car engine sensor. Thank you very much

[@MedSou]

thank you 👍👍👍

[@grahambambrook313]

I was given a Tektronix 7403N which I am having trouble getting to work. I just bought one of these so I can check various wave forms against the operator's manual. I hope a simple, qualitative measurement will help in the restoration as I cannot figure out why I am getting no trace at the moment. I got all the DC rails up to voltage and stable but I do not get full potential on CRT. :-(

[@jackietrove4637]

Is there any way to get the FFT function out of this meter, perhaps by exporting data to a laptop and running it through some a software program?

[@lmt200ish]

Would this be sensitive enough to test for the outside foil on capacitors? Would be handy if something this small is capable of that.

[@Teckno77]

I have mine set to the same as yours at the beggining and the frequency/cycle etc readings keep dissapearing and dont stay on a constant 50hz like yours. Is this a possible fault with my unit as it seems very inconsistant. Now it's reading 249hz? I have a black model ETEPON series which I think is identical to this one.

[@tarikouba]

How to change the waves forms?

[@ronniepirtlejr2606]

I'm going to guess on the power supply that it's positive Center?

[@youtuuba]

On my scope of this model, I could not get the waveform SAVE and RECALL function to work either. In my own tests, I found this scope worked well, with reliable functionality, display accuracy and measurements, as long as I did not try ans measure signals much outside if the audio frequency range. I thought it might be useful in a technician's toolkit where they only need to work with lower frequencies. I discarded the cheap, short, unshielded test leads that came with the scope, and substituted an inexpensive scope probe...it was a 1X/10X probe, but the scope gave worse results when the probe was set to 10X, so I only use it in the 1X mode. The things that impressed me about this particular scope: - the user interface and controls and display colors and indications are well thought out and coordinated - unlike pretty much ever other inexpensive kit scope, this one has a much more useful form factor, and the nice case coming as part of the kit is very good I would not call this scope a 'toy'. Its functionality is better than many basic analog scopes, and adds some of the useful features of a DSO.

[@lmt200ish]

Was it more stable with the shielded scope probe? At higher HZ I watched your vid as well.

[@neail5466]

Very elaborate...thanks..

[@TeacherBrunoOneil]

I need an osciloscope- I repair tv and notebooks mostly. I cannot afford a two-channel expensive osciloscope right now.. do you guys think this one could be something for me now while I still can't afford a more professional thing ? or maybe there is another better model out there for the same amount of money ? thanks for the answers in advance.

[@normdoty]

not a bad little deal. thanks for the video. looks good for some small jobs. if they add a second channel and external trigger i would MARRY IT. as well as buy one of them and sell my tektronics scope. when in ground mode the trace looks like it's responding to your voice, interesting problem, is that leakage from something or failure of the internal shielding ?? all in all it looks like a reasonable kit for the price. thanks again for the video. good work..

[@pasantehen]

I also bought that oscilloscope and the truth works very well. But it is limited (according to the designer) up to 200 khz. Is there a way to modify it so that it works up to 1 Mhz or maybe more?

[@nesr8786]

Hi great presentation, about save, try adj +sec/dev to save and trigger + adj to recall .hope it works for you, take care everyone.Mac

[@fralam7791]

First of all, I congratulate you for the very instructive videos, on the occasion I ask for advice on how to view the trend of the wave of a 220V inverter produced by a photovoltaic panel that charges two batteries with a charge regulator , given that with the oscilloscope, like this one, I have seen that the probe cannot exceed 50 v, I await an answer thanks.

[@miketaylor247]

Great Instructions - very well explained - thank you. Built mine and works perfectly - but the instructions that came with it on how to use are terrible.

[@Dj.julien.b]

I bought one of those and after a few second I get a blinking white screen ... I am pretty confident about the assembly though ..

[@matejzeman7765]

I actually modified this exact osciloscope to be portable. :) Battery life with 700mAh battery is decent and after bit of volta smoothing of the boost converter its quite good :) There is enough space to fit the battery along with charger and boost converter inside. :)

[@electroLuke]

Iv'e been working on that to but something bad happened to my LCD, it randomly stopped displaying anything other than just white screen and I'm quite sure it is hardware problem, because LCD's driver side gets very hot. It's holding my project back...

[@matejzeman7765]

Go back to checking test pins voltages. :)

[@joshuaboneta]

Which boost converter did you use?

[@stclairstclair]

Is this scope more capable than the DSO138? I built the 138 and loved it, now want a used real scope.

Can I use on a 120v 240v inverter ups. All I want is something cheap to see if this one I got is pure sine or square wave. There is no markings

[@nofuss3947]

i'm also trying to get that info... maybe I will have to try it...

[@youtuuba]

Therram, good for you in pointing out that, in spite of JYETech's specifications that say the bandwidth is up to 200kHz, that practically it is only really reliable in the audio range (up to 20kHz), and perhaps as high as around 50kHz if you are careful. Beyond that, it will display some very misleading waveforms. Also good that you mentioned that the power supply is NOT included, but is required to make this work. I think you forgot to mention that the supply needs to have a 5.5x2.1mm sized barrel connector in order to fit the jack on the scope. It really should bu just any old 9V supply....it should be a regulated 9V supply, in order ot prevent accidental damage to the scope circuitry. I also recommend spending a few more dollars for a basic oscilloscope probe, rather then the cheapo unshielded set of test leads that are included with the kit. I wrote my own detailed, enhanced user's manual, and anyone interested can download the PDF of it from here: www.serpentwebsite.com/fileshare.htm (it is at the bottom of the list).

[@raserino614]

Thank you for the manual, it is very helpful!

[@Antagon666]

Better idea is buying Hantek 6022be and connecting it via otg to phone with H scope app. It's only 60$, but it has 2 channels and 20MHz bandwidth.

[@arsayu]

To save keep V/DIV and ADJ. To recall kepp SEC/DIV and ADJ

[@MrBeen992]

Why no one specifies the polarity of the power supply like it does not matter ?????

[@deeznuttz7980]

Just bought mine yesterday and there's no signal

[@TCM890]

Hi, I've recently bought one of these, but when plugging it in I got a white screen and a burning smell from one of the chips on the back. I thought this was just a defective unit, but my replacement has just arrived and it also has a white screen! I'm sure these aren't fakes, and I'm definitely using a 9V power supply - but it is 1.3A. Could it be the current is too high? cheers

[@steverussell1215]

It's not your power supply (assuming it's a regulated supply). From your description, the supply is *capable* of supplying 1.3A at 9V. Whatever you connect it to will only draw the current it needs - I doubt this scope needs more than maybe 50mA or so - maybe 100mA. It does need to be a regulated supply though. An unregulated supply of 9V that is capable of delivering 1.3A may easily be 10 or 11V or even more if a smaller current is being drawn. There are lots of warnings that voltages greater than 10V can damage the device. One other problem might be if the supply were connected incorrectly (wrong polarity) but the schematic shows that this is protected against by a diode so this is not the problem.

[@annemariemiguel2541]

Make sure that the power supply is the correct polarity

[@sd906238]

Can I use aluminum foil as shielding?

[@Artwithbenji]

Yup, copper just works better... also if you are not using aluminum tape you will need to add an adhesive

[@Pkdimmock]

@@koushiroizumi0 It does. I ended up getting the Mustool MT8206 from ebay for £40. Its almost identical to Liumy Graphical multimeter which is £80-90. I have done some research and found that these are not really Oscilloscopes but just Graphical meters.

[@koushiroizumi0]

@@Pkdimmock so how does the MT8206 do in terms of detecting clipping?

[@Pkdimmock]

@@koushiroizumi0 I have not used it yet. Still in the process of fitting door speakers and running 0gauge cable. Will be setting my gains soon. But from the vids I have seen the graphical is good and can def see when the wave starts to clip. They compared it expensive Oscpoes and the SMD dd+1 and it detects accurately compared to them. I will be using it in the next few days. Can keep you updated.

electroLuke I would like to say that osc is too cheap, dont pay even The display.

[@electroLuke]

Well some of us are just hobbyists, not professionals, so this oscilloscope does the job if you want to get a bit deeper into electronics. It's hard to afford real oscilloscope, when you look at it as a hobby.

[@paulchapman603]

Pretty sure he's saying that you get the whole oscilloscope for less than the cost of a display. Not a criticism.

Assembled ones are available for about the same price as the kits. Buy an assembled one, it's not a fun job to put together.

I enjoy building kits.

[@rsattahip]

I used to like to build kits but the Chinese ones come with very poor and sometimes even no instructions. Good luck to you, and enjoy yourself cheers.

[@1pcfred]

The instructions for this particular kit are excellent. There are many build videos on KZbin too. Someone should watch some of them before they try to assemble this kit. There are a couple tricky aspects of it. Like the rotary switch.

[@kaffetrakter4174]

I am look for something cheap to see soundwaves (tuning amplifiers, use this to see when the sound clips), and diagnose cars, for example O2sensors and ABS sensors. Will this unit work fine for this?
