2. Take out the Revolution Index encoder board from Rotor.
3. Fix the new board with Rotor by matching the slot in the Round segment
encoder. Do not touch the Encoder.
4. Connect 10Pin FRC cable with Revolution index encoder board.
5. Switch ON the Balancer. Run Wheel Tracking test (Ref. Chapter 4.4) &
Duty cycle test (Ref. Chapter 4.9) to ensure the functions are OK.
6. Calibrate the Balancer as explained in Operating manual.
7. Run the Balancing program and ensure the functions are working
properly without any errors.
