Are you trying to say you didnt get Block diagrams and schematics of the Aplab LCR meter? If yes, how can you expect a public company to expose its bussiness secrets?
 

Re: digital LCR meter

hello supi ,
i am not aware of the internals of the autocomput lcr meter.but i can give you the basic method ,which was seen from a very old digital lcr meter. a sinewave of known voltage and frequency is generated.(digtally).passed through the 'component under test'. current and its phase shift is measured in 'cut'.
computation of reqd parameters(L /C, R ) and other values is done . (usually in a microprocessor or microcontroller). and displayed.
