Stylus
2.5mm AF
Spring pressure within the probe causes the stylus
to sit in one unique position, and return to this position
following each stylus deflection.
Stylus pressure is set by Renishaw.
The user should only adjust spring pressure in special
circumstances e.g. excessive machine vibration or
insufficient pressure to support the stylus weight.
To adjust spring pressure, remove the probe head to
gain access to the spring pressure adjusting screw.
Slacken the locknut, and turn the adjusting screw
anticlockwise to reduce pressure (more sensitive)
or clockwise to increase pressure (less sensitive).
A stop prevents damage, which could be caused
by overtightening the adjusting screw.
Finally tighten the locknut to 1Nm (0.74lbf.ft) and
replace the probe head.
