pic16f628 lc meter

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!

Are there any comments in this design?

I built this. It measure from 0,1 pF to ~3 uF. I used capasitor ~1000 nF and added trimer 5-30 pF. After calibration using capasitor measured on factory meter, I have ~1% accuracy.

fcl meter

Hello
One of the best LC meter I had seen on the net[as precision] is from Russia.On this page is placed as www.cqham.ru/lcmeter3.htm .To understand the text must go to www.translate.ru/eng/ .They have free on line translator for web pages.The only things that are to be made-select "translate WWW',select "translate Russian to English' and finally to introduce the above adress[www.cqham.ru/lcmeter3.htm ].There is an limitation-the translated page cannot be saved!Now a version of Hex file for Pic16F628[as substitute for Pic16f84] is available at https://Andylab.narod.ru.
