Hommel Tester T1000 Adjustment Procedure?

Wondering if any of you folks are familiar with Hommelwerke profilometers. I have a unit here that measures fine on our standard via the stylus and linearity checks, but the calibration side is a bit high for tolerance and there is not an adjustment procedure in the manual and I've had no luck getting in contact with the manufacturer with how to adjust this :/

Any feedback would be appreciated; I'm still a bit new to this calibration game and my direct peers have no experience with this type of gage.
