Nope, won´t work too, if you attempt to get me directly to something.
But I know what you mean, I´ll look later at Tong Hui offers.
The "twinbrother" ST2830 from sourcetronic here in germany cost about 1200€ incl VAT, a little bit too much.

Just go to AliExpress a search for TH2830, Beich should show up.

Best,

Absolutely and this is why I´m doing this thing here.
To find out what´s going on.
The circuit design of the ET4410 is not bad, not simple(actually) and have an advantage against LCRs with chipset like DE5000, it´s "discrete"..
I must have a look in my "store" if there are caps here over 1000µ, otherwise I connect several together.

Too busy at work at the moment, but won´t be forgotten....
Also the re-drawing of the circuit of the ET4410 is "paused" for time reasons.
Both, the measure of a "big" cap and circuit drawing, will be continued in a few weeks.
There is still an ambition to find out where the weakness of the ET4410 is.
I got a "belly-feeling" that buying another relative cheap lcr bridge won´t get me further in this case.
So the ET4510 will be my favourite if I decide to buy another one because of it´s "seamless" testfrequencies and outputvoltages.
Rest of the circuit should be the same so I can continue drawing the schematic if time will allow it and as long as I got the 4410.
The sourcetronic/tonghui is clearly more nicebuilding but costs more than double and as mentioned before, chances are high that they won´t get me further what accuracy in higher testfrequencies concerns.
Must look if our sourcetronic still got warranty - if not, I´ll open up it´s case and take pics.. 8)

Hi,

That could last a little bit longer - A hioki lcr meter claimed as defect is on it´s way to me... 8)
But it will be not forgotten, still I want to buy a ET4510, nevertheless if I could repair the hioki or not.

hello Martin, I took an ET4410, I read the whole topic and in the end I think it is a good tool lcr.
If then you can make the circuit to improve let me know...thanks

Hi,

Mad as I am I´ve bought a ET4410 again*, a few minutes ago - I couldn´t withstand any longer.. ;)
I want to complete the schematic plus I got some ideas for a possible improvement.
Should arrive in the next 3...4 weeks (china warehouse)

*(sold the first for getting the hioki)

Nice surprise, I´ll have it next thursday...That is pretty fast.
I´m very curious about the inside, will I get again a version where all Ic´s are clear to read...

Always wondered if some folks do this (erase IC identifications) to hide their IP, or to hide the fact they copied someone else's  :o

Edit: added for clarity above.

Best,

Yepp, again I got a version with all parts readable.
But it looks different than mine before....
I think, pictures from the inside and further documentations of the circuit I´ll post in the other thread - As long as it have nothing to do with the title here.

Hello. I'm sitting at work, I'm bored, I started reading this topic, I've read so far to the fourth page. I love discussions like this about capacitors and measuring their parameters.

Of the devices, I have a DerEE DE-5000 for a long time and this year I also bought a desktop RuoShui 4091C.

When I first bought the DE-5000, I was making measurements of Soviet capacitors, and I have a lot of such capacitors, a whole collection.
Here is a part of the measured capacitors:



I'm thinking of continuing to measure all my capacitors, and also in comparison of these two devices and with photos of the capacitors themselves, how appropriate would it be here?
