New rig up and running.

Cpu vdd adjust voltage in 0.0125v steps
Cpu v adjust voltage(offset) in 0.01v steps centered on Cpu vdd

Example

Cpu Vdd = 1.3625
Cpu v- = 1.352 / Cpu v+ = 1.372

If you raise Cpu Vdd = 1.375
Cpu v = 1.365v or 1.385v
depending if you added or subtracted voltage in first step

Thank you, makes much more sense now.
