When measuring leakage current through a 34401 DMM using 6626A power supply the setup shows less than 1uA open circuit @ 4.2V. When using the same setup with N6733B or N6761A power supply modules the open circuit current is 92uA and 42uA respectively when power supply voltage is 4.2V.
Is this to be expected? The setup is sensed to the DUT using 18 gauge wire less than 2 meters in length.

How do you have the measurement set up? Can you show a diagram?
