Not sure what to record! 

All calibrated around the same time. Three readings taken on each instrument with swapped leads and probes all fairly consistent with photo.

Then move to a socket opened up using same leads;

    they wont be the same, but they may become more closely bunched. The 0.7 ohm cluster is almost spread over the full official spec - should be 5% +/- 5 digits, so 0.7 +-0.035+.05 or any where between 0.7+/-0.085  covers 0.615 to 0.785, while the measured spread is .77-.64 or 130 miliohms

    The spread on the lower readings is almost the same, with the newer '71 unit reading about 180 milliohms below the higher of the others - which to me says systematic error, like leads.
