Not sure what software version you have. We are on version 5.8 on our cp2000's. Our press is a 2006 so i know this version is old.
To get to the screen to see the actual values and set the potentiometer I use:
Service, then on the far right you see diagnostic, hit that
from diagnostic on the very top around 3 over you see what looks like a computer, hit that
This brings you to the screen for all your boards/modules, motor, input outputs, CANBus etc.
Towards the center left you'll see the tab/icon "service drive" hit that
Now you will all see your SSK boards/modules, our press has 4, ssk 1, ssk 2 etc. from there you can pick whatever servo (example- lateral register 5th unit etc ) you're setting your POT too, the servo's are listed on the left with values will be listed on the right.
I hope this helps, I know it can be different from press to press
