7.
Each of the four screws B will move the
probe relative to the shank, in the X or Y
direction as pressure is applied.
Tighten individually, backing off after
each movement.
8.
When the stylus tip run-out is less than
20µm, fully tighten screws C to 6 - 8 Nm
(4.4 - 5.9 lbf.ft).
9.
For final centering use screws B to move
the probe, progressively slackening on
one side and tightening the opposite screw,
as the final setting is approached, using
two hexagon keys.
Tip run out of 5µm (0.0002 in) should
be achievable.
10. It is important that all four screws B are
tight or tightened to 1,5 - 3,5 Nm
(1.1 - 2.6 lbf.ft) once the final setting
has been achieved.
11. When on-centre adjustment is completed,
replace battery and covers - see opposite.
