Installing the Stylus
1 Locate the stylus and stylus exchange tool in Box 3. Each stylus is shipped in its own protective plastic
case.
2 The exchange tool is designed to magnetically hold the stylus until it is seated in the sensor head. Turn the
thumb wheel on the exchange tool so that the green dot (see
Figure 2-24
) is NOT visible (that is, the
magnet is disengaged).
3 Open the stylus case, and gently remove the stylus. Lift the stylus by its central disk, not by the beam.
4 Place the stylus into the exchange tool, such that the round disk is aligned with the silver magnet on the
tool. The stylus arm must be centered within the long trench (see
Figure 2-24
). The stylus tip should point
down.
