centre line need only be approximate,
except in the following circumstances.
1. When probe vector software is used.
2. When the machine control software
cannot compensate for an offset stylus.
3. The stylus must be parallel to
the spindle axis to prevent stylus stem
contact against the side of deep holes.

STYLUS ON-CENTRE ADJUSTMENT
1. If adjustment is required, remove
the battery covers and battery.
2. Slacken the two probe/shank
clamping screws half of one turn,
so that the disc washers maintain
a slight clamping grip.
3. There are four adjusting screws A.
Each will move the probe relative
to the shank, in the X or Y direction
as pressure is applied.
Tighten individually. Back off after
each movement.
4. When stylus target position is obtained,
tighten all screws - see page 30.
5. Replace battery and battery covers.
