I have to measure changes in resistance to the 3rd or 4th decimal, for ex 3.0145.
I am using a 4 wire measurement with a very good constant current source. I have a 16bit DAQ device to measure the voltage.
I keep getting questions on why one would be used over the other. I have trying to get this answer from various forums but I still keep getting doubts.
Would love if somebody explained this and which to use as plainly as possible. A discussion on the advantages and disadvantages would be great as well.
