6.3 Setting the zero point
The zero point is the gap width at which the fixed and the
movable grinding disks rub each other lightly; thus there is
no gap. Starting from this zero point, all other gap widths
are controlled.
Whenever the grinding disks are exchanged, the zero point
needs to be reset. Grinding disks may have different thick‐
nesses depending on the wear.
