Hello experts I want to make an inductance ,capacitance & Resistance meter ?

what is the principle behind each one ?

any reference design ?
thanks in adance

Google is your friend.

Check out this discussion (and the product discussed)...

The circuit is quite simple, and all the "magic" is done in the software.
That is the way it is done here in the 21st century.
But if you want to study the 19th century historical methods and gear, as JoeO suggests, Google (and Wikipedia, et.al.) will reveal enough information to keep you reading for months.

He said he wanted to "make" one.   You told him how to buy one.
How is buying one or reading the forum going to explain the principle behind each one?
Since when is a 328 based LCR meter a "reference design"?

Is it too much for someone to at least do minimal research before coming on here and asking an open ended question?
A poster should at least make a minimum attempt to research some topics for himself.

No. I did not suggest that he BUY anything. I suggested that the $20 circuit, software (which is open-source) and discussion would have potential benefit if he was researching how to build his own LCR meter. 

Based on popularity and novelty, I submit that the $20 LCRetc. meter IS a 21st century "reference design".
Or do you think a "reference design" is something that is 100 years old and based on firebottles? 
Think outside the box.  Perhaps the box is a different shape and larger size here in the 21st century.

I also suggested that the old original concepts and circuits were also available by spending a few quality milliseconds with Google.
