So,
Recently, I've been interested about milli-Ohm meters, because simply put: DMMs are not able to measure resistance accurately down to the milli/micro ohm range. The bad news is that low ohm values are really susceptible at temperature changes because when things warm up, they increase the resistance, and if you get a decent gear in a properly set up, it will compensate the result value for precision testing.
The point is, I don't understand if milliOhm meters can be replaced with Impeadence analyzer: I know, they surely can measure DC resistance, down to the micro Ohm range, and they can also compensate the temperature. So, what's the deal with having a MilliOhm meter, compared to an Impeadence analyzer (beside, the fact that Impeadence analyzers can measure other parameters?)? What I'm missing
?
Apparently, also, the test current is much lower with milliOhm meters, and this will prevent the resistance to change.
