Calibration Procedure for the Vibration Sensors
Note: Calibration of the Vibration Sensor is necessary upon initial Start-up. Calibration of the Vibration Sensor is necessary whenever the Comm/Accel Board is replaced. The RPS Advance Setpoint Calibration must be performed whenever the Comm/Accel Assembly is replaced and whenever the top bearing of the flywheel is replaced. Refer to Systems Operation/Testing and Adjusting, "Rotor Position Sensor - Calibrate".
