Switzerland, a land of precision: terrific, he must have a friend who knows about TT setup.

They recommend a digital gauge to set stylus force (no interference with magnetic bearing, no ’seesaw’ type needed.
Presumably the arm was installed by a pro, and is correct. Hopefully the alignment template was provided to your friend. IF NOT, I would request a template from Clearaudio.
The manual/template shows everything you need to know about mounting the arm, the cartridges’ overhang; and cartridges’ two null point alignments.
arm height a single set screw from the side of the base plate.
to align azimuth, there is a set screw in the bottom of the arm tube near it’s head

anti-skate is inconveniently located below the plinth.

level via adjustable feet must be maintained while in adjustment position with 1 corner ’in outer space’ for access to adjustment screw below. then level re-confirmed when TT moved back to operating location.
After confirmation of arm and cartridge: IF the cartridge will not track within the specified range 1.4g to 1.7g something is wrong, EVEN IF it sounds GREAT.
Note: anti-skate needs to be reduced to zero from below BEFORE adjusting tracking force; then add tracking force; then back below to ’add’ anti-skate as final setting.
Note: ANY subsequent adjustment of tracking force: anti-skate needs to be reduced to zero again, tracking force set; anti-skate set.

basic confirmation:
1. suppose arm mounting and cartridge mounting (overhang/two null points), azimuth, arm height are verified correctly. (or correct them).
2. anti-skate needs to be reduced to zero before step 3.
3. tracking force set to 1.7g max with digital gauge
4. ’add’ anti-skate.
a. blank disc method
b. Clearaudios’ Trackability Test Record
We recommend the Clearaudio Trackablity Test Record available from www.analogshop.de or from your specialist retailer for a professional and perfect anti-skating setting.
