I don't think there is a set place to start so I recommend the following... start with a level table and raise the pivot end of the arm until high frequenies are not reproduced properly then gradually lower until the highs are pure and the bass and sound stage slam and expand.
That's as easy as it gets, it takes a bit of time unless you are using a Rega cartridge then the arm is automatically set for correct VTA!
