**broken link removed** you can find a project similar to Elektor's, but in which the realy has been replaced by 74HC4053.
**broken link removed** is the source tree of the project.
It contains a fix for the analog part so that 4053 does not affect the measurment...
Hello.
I need a service manual w/ schematics for the URV-3 millivolt meter by Rohde & Scwarz. Or just schematics would do too. What's important is to have the values for all components etc.
And, the URV-3 is often mistaken with the URV or the URV-3-2, which is a totally different thing. I need...
hb24208
I've got an HB24208, and I want to use it. Searching for all kind of information about it on the net gave no results. At the **broken link removed**, there is nothing about the old text LCDs. The only thing I found was this post, which I realised that this LCD has a serial SPI interface...

In the russian forum has published a new version of the RLC meter: **broken link removed**
Full documentation for this project: **broken link removed**
RLC-2 not used DSP method, but meassure R,Ls,Cs,Lp,Cp,Q,D with great precision.
miliohm meter schema
I have not seen such a project in Russian sites. Perhaps because of AD integrated circuits are more expensive and difficult to find the Russian market.
If you see such a project will post link.
best regards,

Congratulations narccizzo, very nice construction. Respect!
Into original shematic have problem with Ron 4053 swith. It is depending on temperature. If make new construction, replace input shematic with this **broken link removed** In this way input work better, but need...
rlc meter schematic circuit
I've found this project from Circuit cellar:
**broken link removed** it uses new parts and the same technology as Elektor's project.
advanced lcr meter elektor
I also have the shematic of RLC9000 but it build with many ICs. I want to make sample RLC like **broken link removed** (PeakTech 2165) and it **broken link removed**. But it used two terminal wires to meassure DUT. Good measurment result when use four terminal...
lc meter elektor
Kripton2035,
Thank you for your replay! I see this manual but here there is only top plane of PCBs, and quality of pictures is not good. (Wires are not seable) To make shematic I need both PCBs plane - TOP and BOTTOM. If I make the shematic I upload it in forum. Please help...
lcr meter,dsp
Kripton2035, i am happy that the bought kit is working properly. Wold you make some pictures of the PCBs with good quality and post them - by them i could recreate the way of the schematic. Thank you before!

70% of the good LCR meter is the good pcb and the well made analog part of the circuit. The soft of the controller isn't a big problem. As i wrote upper am making a project of an LCR meter with C8051F410 and I have almost finished the program for the controller. Most of the problems...
rlc meter design plan
In the Russian forum a man wriote that he has realised successfully:**broken link removed** and **broken link removed**. The LCD must be screened and a ferrite must be placed **broken link removed**. I saw an interesting RLC meter kit with good parameters:

lrc meter elektor
I am not making Gints Oleg's project, and I am not going to make it for now on. From a post replay in the russian forum I understood that the people who are replying the project have problems and for now on there isn't a successfully replyed project. If someone completes the...
