I am measuring Picotest Kit 1 milliohm resistor using 2 Port Shunt Thru method using Picotest Common Mode Isolator. As shown below above the low frequency range I am measuring a base of approx. 400uOhms instead of 1milliohms. Full 2 Port Calibration is performed. Noise floor was in the 10s of uOhms range. Mounting impedance is of course not accounted for but that should have increased the impedance rather than decrease? What am I doing wrong?
