Figure 6-60 The Mini-Wheel encoder installed on the alternate encoder holder
12. Tighten the screw that fixes the Mini-Wheel encoder to the alternate encoder
holder.
Make sure that the tension in the Mini-Wheel encoder’s spring is sufficient enough to
ensure proper contact with the acoustic wheel at all times, without impairing the
acoustic wheel’s rotation.
When you relocate the Mini-Wheel encoder to the alternate encoder holder on the
RollerFORM in order to perform axial (longitudinal) scans on convex surfaces, you
must perform an encoder calibration. Please refer to the instrument user’s manual.
