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
20 µm, 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
oneside and tightening the opposite
screw, as the final setting is approached,
using two hexagon keys.
Tip run out of 5 µm (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
page 1-13.
