Most times when you want to measure down at the milliohm level you use a
Kelvin milliohm meter. This has 4 measurement contacts. Essentially, one
pair drive a current, the second pair does the sensing. This way lead
effects are minimised.
There are several meters like this on the market from the usual players.
Cheers,
Derek.
