The alternate encoder position is not recommended for inspecting narrow parts, or for
inspecting pipes axially (longitudinally), because the resolution of the encoder
changes if the tire compression varies.
To relocate the Mini-Wheel encoder on the alternate encoder holder
1. Using the hexagonal key, loosen the rear roller’s retaining screw (see Figure 6-52
on page 126).

2. Gently apply pressure to the rear roller’s axle on the end opposite the retaining
screw to free it from its seat in the RollerFORM frame (see Figure 6-53 on
page 127).
