CAUTION: Always hold the support bar
in position to counteract twisting forces
and avoid over-stressing the stylus
break stem.
Additional setting for square styli
Stylus level setting is the same for disc
and square styli. In addition, square
styli side faces can be aligned with the
machine’s X/Y axes.
Coarse rotational adjustment is
obtained by slackening the stylus holder
grubscrew A (see page 16), rotating
the stylus in its holder, then retightening
grubscrew A. (Always use the support
bar – see page 17.)
Fine rotational adjustment is obtained
by loosening the four grubscrews R1
and alternately adjusting the two probe
rotational adjuster screws R2 and R3
until the required tip parallelism to the
axes is achieved. Retighten grubscrews
R1, R2 and R3.
CAUTION: Ensure all screws are tight
after adjustment.
