Recently, I found a R-L-C Meter called Smart Tweezers R-L-C Meter from the website of http://www.advancedevices.com/products_tw.htm" [Broken]. It is quite similar to the Chinese Chopsticks that can be used to take measurements from the devices already mounted on a board. For the through-hole devices, we should desolder one of the legs (two-pin components) in order to measure the specified value, said R value, correctly. However, it can take the measurement directly without any desoldering process. Is it accurate enough? Any comment?
