If anybody wants to see a comparative measurement between a Rohde & Schwarz HM8118 (2.700€) and the RuoShui 4090C (240€), please contact me. Summarized, it can be said, that the RuoShui 4090C has a very decent accuracy for its price. If you are a hobbyist, do not hesitate to buy it. I also have the User Manual and the SCPI Command Reference in digital format.
Thank you Lukas! yes i would be interested in both your test and the extra documentation. can you sent me an email thank you very much!
@@TonyAlbus Hi, I sent you the documents. Maybe you can share them on a cloud with the link in the video description!
@@LukasZ328 Thank you for the documents, yes it will share it, the link is in the video description.
@@TonyAlbus perfect. Thanks for the credits!
After some weeks of use, I am so impressed with the RuoShui VC4090C!
+Good accuracy in comparison with the Rohde & Schwarz HM8118
+Decent Display you can read from all angles with a GUI like you would expect
+Can measure all needed parameters, also for professional applications (even the imaginary part of the impedance: X)
+Supports SCPI commands
+Has a working PC App if you run it as Administrator. Thereby you can use both, RS232 and USB.
+East Tester covers the hole for the USB, RuoShui does not. They use a suitable front panel.
+Once you have an LCR Meter on your bench, you will use it permanently, especially when you are repairing devices or when you design filters.
-The BNC connectors of included Kelvin Clip Leads have very low quality
-No functionality to measure transformers but how many people out there do this actually need?
Thank you Lukas for your review, i totally agree and thank you for all extra information!.
thank you Tony. I bought hantek 1833c and I think it is as good as this machine which you are introducing. I am also thinking to buy uni-t 622e, do you recommend it?
The Hantek 1833 is very nice indeed, the uni-t i have not tested, but i have still an EastTester portable in my queue to show on video ET432
All those meters are just a vanity. They do nothing for you. You can do the same with a $20 bucks tester or make your own for few bucks
Thank you
Hi Tony. I've become a huge fan of your channel. You do an absolutely insane amount of reviews. Much appreciated 🙏
Any chance you could review the ET4510? Or rather one the ET45XX variants. They seem to be similar to the ET4410 with adjustable frequency and some other such features. I'm super curious what they look like inside too and if it is simply an ET4410 with different software. I'd have no problem ordering one but I think the internet is in need of an actual useful review of them and you are the only reviewer basically reviewing just about everything these days.
Hi, thank you so much for the nice comment. For now, EastTester or Victor do not send me free stuff to review yet. so when an item is not at Eleshop for borrow, it means i need to buy it myself or wait for a donation. in this case i already have the ET4410 so buying it myself is not an option for now. so i hope EastTester and or Victor will find my channel soon :)
Hi, Is there any softwaere to transfer the data from ET4410 to the computer. Thanks.
Yes the software is in the video description, you need to run in XP compatible mode
Thanks for posting the video. Defpom did a video on the East Tester ET4401. It is the 10 kHz max version. It looks pretty much the same both inside and out and it has the same metal case. The East Tester does come with rubber corner guards on the outside of the case. I actually like the front panel color scheme better than the RuoShui but covering the USB and the power switch do look better on your unit. I am going with the East Tester 100 kHz max version on Aliexpress and at this time with shipping goes for around $270.00 USD. One comment on the electrolytic capacitor measurement. I think you might have the wrong test frequency selected. I can not see the value from your video (1kHz???) which will effect the resulting measured value. Usually smoothing caps are measured at 100 or 120 Hz to simulate full-wave rectified line frequencies of 50 or 60 Hz. Also I am not sure mine will have the English user manual so thank you very much for taking the time to post your manual... much appreciated!
Hello Jwrtiger, thanks you for your comments, yes that makes sense for bigger Caps to use a lower freq, good point, i used it now in automode and did not read, just wanted to test it asap :-).. Hope yours arrives soon and welcome for the manual..
Danke für dein Video. Mehr Nahaufnahmen wäre besser.
Thank you for the feedback!
Could you test what maximum capacitance the two meters can test? RuoShui say max 9999 uF in the data sheet, which is rather low. EastTester say 99.999 mF which would be more ok.
Both machines are the same, you see that when i open them... would like to help you, but don't have caps that big.
I now got a RuoShui 4091C. It had no problem measure a 47,000 uF capacitor. With a 330,000 it had problem, but I am not too suprised. 47,000 uF covers 99% of my needs so all ok.
@@aronake Thank for coming back at this.. this is usefull for others also..
Hello there Mr tony, nice device you got this time, it seems to be very accurate, do you have a specific use for it? because it's very expensive for the difference in price compared to a good multimeter
Hello Yuri, for accuracy you need the 4 leads connection , the calvin clips, some DMM can do Capacity not to many can do Inductance... also the frequency it does it samples on, makes it can do a very large range of values.
More volume pls 👍
Thanks for your feedback, done that in my newer videos, this one is 2 years old.
When you start shelving out the window bay 😃
LOL..yes need space :)
Понятный обзор для начального знакомства с прибором.
Спасибо!
Oh dear, now you have to arrange the equipment stacks again...
Haha, yeps... think the marconi counter needs to move to secondary position, the LCR fits nice ontop of the 2955... the endless tetris :)
Hi tony try a wirewound resistor ti see if it gonna recognize it as resistor.
Hello Kyo, yes that is indeed a very nice test, Thank you!
Will do that in one of my QA videos.
Nice piece of equipment
Thank you, Yes i was also happely supprised it looked this good.
Hello Tony. I would like to share additional information on connecting and using the ET4400 bridge meter with a personal computer. I can't install a driver for Windows 7. The message "Error reading setu initialization file" appears. I suggest you jointly explore the possibility of the device to work in conjunction with a personal computer. Here is a link to software courtesy of East Tester yadi.sk/d/rk7M00ljaVVspg?w=1
Thank you, yes i will try this, it will appear later in the QA video, keep an eye... Tony
hi, I am new to this, but I bought et4401, do you have labview sample program to control et44 series?
Hi Adri, i don't use that yet. so i have not collected that info
I'm wondering when you need to measure at 100khz instead of 10 kHz. My guess is to measure smaller capacitance or inductance ? I'm a noob so please enlighten me. The similar device with a frequency range up to 10khz is a fair bit amount cheaper.
Hi, thanks for you question..maybe this can help: www.eevblog.com/forum/beginners/lrc-meter-different-readings-at-different-frequencies-why/
But basicly.if you meseure on more frequencies you could get a better acuracy .
@@TonyAlbus Electrolytics are generally tested at 100/120Hz by manufacturers, so going to a higher frequency could result in lower accuracy on the electrolytics. Electrolytics are generally not used for high frequency use.
@@nikmilosevic1696 Yes correct, thanks for sharing
