snoopy I gave you 100 points for the translation as I said some months ago. many thanks.

I need software for LRC meter published in Elektor 4,5,6/1997. Can somebody upload?

You may find another FCL meter project (PIC Micro-controller based)at https://hamradio.in/circuits/fcl.php the relevent sotware is also in the same site.

measurement of R may not be difficult with any DMM.

Thank Kripton2035!
Tried to compile the file, with MPLab? There are errors which I don't understand!

it is a nice meter but
this meter is really not precise enought for what we are discussing here... sorry.
we want to measure the milliohm...

did not have time to do it yet but I will soon give it a try !
 

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.
 

lcr meter software

Maybe you may want to look at my simple LC meter with a Atmel attiny2313, asm source included. Based on the "Amateur Radio Magazine" april 2004.

**broken link removed**

I'm sorry the page is still in Dutch, but google will translate it.

attiny2313 lc meter

sorry but as said some posts ago we want to measure L C and R. your meter doesnt measure R
we also want to measure the milliohm, as elektor did 10 years ago with a dsp
thanks for your message but it's not for this thread.
 

elektor r-l-c soft

Hi guys,

I am already done with the russian design and I am very satisfied with the performance of this tester, actually I made my own PCB design in eagle.

Thanks to Gints Oleg for sharing the plans of this simple great tool!

elektor software june 2008

very nice narccizzo ...
can you post some picture(s) and upload us the schematic and firmware files you used to achieve your design ??? as there are lots of files on the russian site, I dont know which one to use !
best regards,
 

elektor rlc software june 2008

You can trust all the original design (except by a small error in the macro delay in the software), my design still needs some small details but anyway this is what I have so far. I had to make some small changes in the sofware but now you can assemble it without problems, follow and understand easily how the meter works. you can try to build the circuit in the protoboard It works fine on it.
I am still going to make another small changes. Take a look guys and say what do you think.
This design looks to be very easy to improve some changes and add some features like a 10KHz test, if any is interested is welcome.

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 additional IC 4053. Here have complite construction with this input shematic.

Is someone tried to start compiling a dsPIC RLC project of Circuit Cellar into MPLAB? I get error messages from the compiler. I can not understand what is the problem. Please help me.

Can you say what some Microcontroller is used in MV1008?

best regards,

Elektor used adg433 from analog devices to switch instead of the 4053. did some russian people try to use also this circuit to replace the 4053 ???
 

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,
 

+lcr +meter +kit

The complete work in action...



Now I'm going to fix the temp issue and make all the internal calibration easier.

All project files are contained in the LCR 0.9.rar file posted above. The voltage reference IC is MCP1541 (4096mV). Any question or suggestion.. let me know.

Regards.

hi,
as this version is not proven to work correctly, I have stopped the translation work...and I'm now planning to buy the kit from mwinstruments, better chances to work correctly. the precision of the lcr meter is critical... 150 euros for the kit is really cheap for that kind of instrument i think.

If R is not a must, why not try for Phil Rice(Australia) version of LC Meter2. he has given full info in his websites.

**broken link removed**

though a total shift from 8051 series. the design with 16F628 appeals to me as optimal design. Full support and source code provided.

The original version is from Niel of US and he claims to have measured 1pF and 1n(nano)H on his LC Meter II B . and he sells Kits and ready made even. look at www.aade.com ( no source code and the Chip is code protected)


all the best,
Sarma

@mvs sarma:
as you can see the title of this thread is "LCR meter", and not "LC meter" ... there are lots of threads with this LC meter and all the derivatives, open source or not.
but this is not our quest... we want an lcr meter as good as the lcr meter that elektor formerly described with a analog devices dsp as main component and that was able to measure the milliohm.

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.
 

ru lcr meter

hi pavalbo,

many thanks for this new version;
I think this new meter seems far more complicated than the former one...
is the more precision really worth the complexity ?
I'm not sure...
let's wait for some other people to try this meter...

Hi All!

New version RLC-meter is the more precision to comparing in RLC v.1.
---------------------------------------------------------------------------------
New RLC: Old RLC:
Range R: 0.01 Om – 100 MOm 0.01 Om до 20 MOm
Range L: 0.01 uH – 20 kH 1 uH – 10 kH
Range C: 0.01 pF – 22000 uF 1 pF – 2000 uF
Freq.: 100 Hz, 1 kHz, 10 kHz 100 Hz, 1 kHz
----------------------------------------------------------------------------------

Only 2 parts need find: MAX293 and 74HC390!
