Dear all
Now, we are measure DC resistance of power plane in PCB. The presision should 
be 0.1 mohm at least. However, because of the clamp of the meter, the error is 
about 1m ohm. In another word, the difference between two measurement for the 
same DUT is about 1 mohm. Is there any advice about this topic? Anything will 
be help. In your measurement, how to connect the probe to the plane?

Best Regards
