RE: HP 50g & SD Cards: Performance, Format, Notes
There is difference if you probe the system batteries in or without. If you probe it batteries in it will give different results with different meters, depending on the internal measuring setup of the meter. That is what have tought to me and that is what I noticed. The truth table I gave you is done without any own current flowing inside of the DUT.

In my unit the card case is not connected to the Testpads found on the R66 .. R68 while measuring the device without batteries and while my meter is old it propably beats average handheld Flukes pretty much in any respect input impedance included.

The resistors are following.
R66 - 102
R67,68 - 104
