3.2 Replacing/Mounting a Stylus
This section describes how to replace and mount a stylus.
1. Loosen the fixing screw with the supplied hex wrench (nominal 1.5) and remove it.
2. Insert a stylus into the arm so that there will be no gap, and tighten it with the supplied
hex wrench (nominal 1.5).
• When mounting a stylus to the arm, insert the stylus until the stylus positioning
stopper reaches the arm.
• When mounting a stylus other than a ball stylus and a cone stylus, be careful of the
stylus mounting direction as shown in the drawing above. Wrong mounting direction
changes the stylus tip radius with respect to the trace direction, and may
accordingly make a measuring error.
• To prevent failure, make sure to replace or mount the stylus while stylus is in free
state or before mounting an arm to the main arm.
