Yea, I have done the DCV first as per verification procedure. Yes, no cables connected, only a LAN cable. I have several times re calibrated ( Fluke 5730A ) the unit but this parameter stays just outside spec. on all of my 4 units. I was in spec the first year (2018)  i did this but after that it keeps failing. Currenly im checking the ppm spec's on the 3706A and the 5730A. How can you tweak the dcv offset?

 

During the re certification of my 3706A, the spec for the uA zero parameter is +/--3.000000E-10. My unit has failing this with a value of 4.400000E-10 or higher, how do i bring this value down. Recalibrating the unit according to the manual is not sufficient to do so.  The recalibrating procedure will pass with no issues. Does anyone have any suggestions please.
