link error Title: Re: lc_meter Post by: gianmagna on January 18, 2008, 10:08:48 22:08 this link is correct ;D http://www.electronics-diy.com/lc_meter.php Title: Re: lc_meter Post by: yahoo on January 19, 2008, 12:36:51 00:36 It's a very accurate LC meter. I have it working from years. Highly recommended! I cannot see the link for the firmware but if somebody is interested I can provide it.

It is still there when I tested the link after your posting. Maybe you should clear the cache in your browser. Title: Re: lc_meter Post by: TA5CT on January 21, 2008, 03:35:21 15:35 you can visit this web page.

Did your try local alarm installer, I get faulty control panels from mine. most are 2x16 but also 4x32 upto 4x40 cost a few beers.some I have put on e-bay :) Title: Re: lc_meter Post by: hodahel on January 28, 2011, 08:20:15 08:20 After how many years..I'm back on this thread to update... ;D
I successfully built my LC Meter... (http://i82.photobucket.com/albums/j249/Rhonn_2006/Image329.jpg) (http://i82.photobucket.com/albums/j249/Rhonn_2006/Image325.jpg) (http://i82.photobucket.com/albums/j249/Rhonn_2006/Image330.jpg) (http://i82.photobucket.com/albums/j249/Rhonn_2006/Image332.jpg) Reading on 33pF ceramic caps.. (http://i82.photobucket.com/albums/j249/Rhonn_2006/Image372.jpg) 15pF.. (http://i82.photobucket.com/albums/j249/Rhonn_2006/Image375.jpg) 2.2nF (http://i82.photobucket.com/albums/j249/Rhonn_2006/Image377.jpg) 1000pF 1nF (http://i82.photobucket.com/albums/j249/Rhonn_2006/Image378.jpg) Seems weird on coil.. here is a reading for 100uH coil. (http://i82.photobucket.com/albums/j249/Rhonn_2006/Image379.jpg) another 100uH (http://i82.photobucket.com/albums/j249/Rhonn_2006/Image380.jpg) I wonder if who's telling the truth...the Coil or the meter? :( @MODS Please Delete if I'm reviving OLD THREAD for no reason... TIA Title: Re: lc_meter Post by: pickit2 on January 28, 2011, 12:59:28 12:59 hodahel
Not a problem with post, but why not post it as a full project in projects forum. Title: Re: lc_meter Post by: hate on January 28, 2011, 05:15:48 17:15 Quote I wonder if who's telling the truth...the Coil or the meter? Sad In a similar version of this project the author inserted a calibration code, I didn't check if there is also one in this one but the heating up time of the components greatly affect measurements. The system must be calibrated after some time after it is powered. I had made the similar project I mentioned and when calibrated after a few minutes after it was powered the errors were acceptable.Regards...

I am thinking of building this one: http://www.hobbielektronika.hu/kapcsolasok/lcm3_alkatresz_mero_muszer_-_kit_lehetoseg.html Sorry, it is hungarian, but you can use google translate: http://translate.google.com/translate?js=n&prev=_t&hl=hu&ie=UTF-8&layout=2&eotf=1&sl=hu&tl=en&u=http%3A%2F%2Fwww.hobbielektronika.hu%2Fkapcsolasok%2Flcm3_alkatresz_mero_muszer_-_kit_lehetoseg.html capacitance 1pF ... 0.1F inductance 10nH ... 20H ESR up to 500mOhm In circuit ESR measurement It measures also the capacitance of inducttors, and correcte the inductance measurement with this.

The system must be calibrated after some time after it is powered. I had made the similar project I mentioned and when calibrated after a few minutes after it was powered the errors were acceptable. This version includes calibration via software...also has the option to manually calibrate to standard value... The problem I encountered with the INDUCTOR side is the coil itself....it was marked with 100uH but reads 82uH...tried other coils and they all give close to printed values reading... are there any links hate for the calibrated version? This is the version I constructed.... http://sites.google.com/site/vk3bhr/home/index2-html Title: Re: lc_meter Post by: hate on January 29, 2011, 11:30:41 11:30 @hodahel: Sry I couldn't notice a button for calibration in ur pics and considered it didn't have calibration. It might be a tolerance and brand issue for the bad readings.
@metal: It's been a long time since I constructed it and don't remember which one I constructed but the hardware was the same with the ones posted here. Probably just a clone. I have the schematic and code though, I can post them if u like. Regards...
