I've made the LC meter using 89c2051 from Hw.cz Site
But it's not working properly
if anybody have made it successfully , kindly provide me the info
Does it measure Capacitance as well as inductance accurately ?
regards,
Shashank P.
oldmp said:I built the LC meter, form EPE feb 2004 issue. It's a simple circuit, but by the C meter part , you need to modify the value of the 10k 1% resistor.... Simple use a 20k, and compensate it from the software... When I used the 10k resistor, the oscillator wan't to start... The compensation is easy to made. Turn on the circuit, and press the nulling button...
I tested it from 1pF !!! up to 4700uF--->> No problems!
I've made a PC version with AADE oscillator and frequency divider (2 x CD4040) because PC time resolution under widow$ is much less accurate than PICSergiu_Q said:Hi
have anyone a LC-meter project (scheme, soft and others ) who can interface with computer ?

Attached is the single sided PCB...I have used two sided with same results..

WOW Yus, that's a VERY cool project! What are the specs of your design?
Also, do you mind sharing the code and schematic so, we can build it.
I saw your discussion at **broken link removed** but the google translator doesn't help me much understanding what's going on
Thanks
