Thanks for reviewing this. I think this meter would be great for automotive use. However, it’s a pity there were issues with the frequency counter. Have you tried increasing the amplitude to see if you have better results? In your video you have set it to 1 volt peak to peak, which is also the minimum mentioned in the manual but perhaps increase it by another half volt or even a bit more to see if anything improves.
In regards to turning the AUTO range back on after cycling through the ranges manually, while I don’t have this exact meter, on my own meter you need to hold down the AUTO button for around 2-3 seconds for it to go back to auto range. So maybe give that a go. Also, please only take this as constructive feedback and not as a bad thing, but when you test high frequencies with an oscilloscope you should use a 50ohm termination on the scopes BNC connector otherwise you could end up getting incorrect results due to what they call “reflections” in the cable. Apart from that thanks again for the review Hugo. I’m starting to get envious of all the test equipment that you have in your workshop now!! Lol. It’s great to see you expanding with all this equipment including that DC voltage calibrator.

Hello! I would like to start to thanking your continuos support, inspiring comments and I do consider them constructive. To give you a context, most of the times I have to record during the night, I have a day time job. Right now is 00:21am, I'm answering you before start recording the brand new FNIRSI DSOX180H oscilloscope... so excited with this one, but back to topic.
The recording of this video ended at 5am, but that's not on the viewer, is on me. Sometimes my judgement is not the same at that hour and sometime I even miss some english words and say it in portuguese, what I mean is, sometimes I miss things because I'm not on my best anymore at that hour but, after reading your comment I did unpack the ET829 again and went testing.
I have to say that I did a mistake in the video, well kind of, I could it test it better with other values/frequencies, so I went back and test it again the frequency and dutty cycle functions and this what I found out:
1) Frequency: It still is bad, but with higher Vpp (ex: 15V) you're able to have it almost right up to 70Khz and that is way more than the 10Khz I showed on the video. So, probably will need the terminator to go further.
2) Dutty cycle: The problem wasn't the Vpp but the frequency, in the video was with 10Khz and that was too much for the device to be able to correctly read the dutty cycle. I tested with lower frequencies and it is fairly accurate up to 2Khz, after that starts to drift again.
3) AUTO function, once again, you're right. After pressing for 2 seconds it went back to auto mode. It is in the manual, but is so many things to read that passed me. Thanks for the tip.
My daytime job is a software engineer and some system administration.
Electronics is a hobby and passion that I have since I was little and that for events in life that I couldn't control at that time, I was not able to follow as a career. So, now, I realized that the things we take from life, are resumed to our life experiences, everything else is left behind.
This is really something I love and when I started to buy equipment for my hobby I realized that his a very big investment to anybody (professional or not).
I made mistakes that cost me a lot of money. I though for myself that, there are people that can't afford this kind of mistakes, the budget has to be spent very carefully. I am from the time of the BBS and community, I used to have one. I decided them to create a channel and community with the purpose to present the equipments, that I have the luck and privilege to receive to review, the best I can and with the most detailed way I can, so if you're interested in something you wish to buy, you can see here and in detail how it works.
I agree that I do make mistakes, but the only persons that don't do mistakes, are the ones that don't act on things, so, live and learn is my motto.
Thats why I bough the DC Voltage Calibrator, so I have a trustfull source of information to know if a device is with the right values, so I can give more accurate information to the viewers. I agree there is a long way to go in the terms of techical knowledge, but everyday I learn so much and people like you are wonderful and share the knowledge in terms of community for helping each other, thats my goal and I feel so blessed to be able to have viewers that like you, care enough to explain and to teach.
Believe me, I will never consider your comment a bad thing. Thanks for watching! 😁

Looks like a good tool for car diagnostics.

[@TechCornerTV]

Hi, yes it is, there are other options in the market, but just saw a Aliexpress promotion of this unit for 99€... crazy! Great price for everything you get. Thanks for watching.

[@johandepauw5969]

Hi, for your voltage testing, i believe that it is better that the leads of your meter should be on the entrance of the testing device and not on the DC source. This is could create a config setup error fault/difference in the result.

[@TechCornerTV]

Hi, avoid errors is always desirable, so I'm trying to understand better what you mean, didn't quite get what do you mean, thanks for watching.

[@kaletsugas]

What oscilloscope would you recommend for use with designing and repairing SMPS?

[@TechCornerTV]

Hello, this was a nice one, I would also recommend the FNIRSIS DSOX180H or the Zeeweii DSO2512G or DSO3D12, off course this in smalll/portable format. Thanks for watching!

[@swingarmer]

Can you measure inductance with this?

[@TechCornerTV]

Hi, nope. There very few multimeters that have that functionality. Normaly you'll need a LCR for that. Thanks for watching.

[@andyweekend4096]

hi hugo , does the meter has an FFT and XY mode

[@TechCornerTV]

Hi Andy, sadly no. Even so is a good pack of functions for the price, I did retest the frequency and dutty cycle (you can see here in the reply to Khoung) and it has some improvements to the test in the video. Thanks for watching!

@@TechCornerTV welcome hugo .

[@cyriloa]

Bonjour, je cherche le logiciel PC pour l'oscilloscope ET829, quelqu'un pourrais me donne un lien de téléchargement? Merci pas avance

[@TechCornerTV]

Hi, not sure if that software exists.... thanks for sharing!

[@fredshead3956]

Thanks for reiew, do you know the voltage of the internal battery, i guess 5 volts?, can you charge it with anormal usb charger, i have a5 volt and a 9 volt charger...Fred in England

[@TechCornerTV]

Hello Fred, you're welcome, glad it was useful. I didn't open this one to see what battery in it, but **normally** will be a 3.7v lithium battery. It is charged by 5V USB type-c. Thanks for watching!
