Set the multimeter to the setting for "PWM%".
Perform the calibration for the joystick. As you perform the calibration, note the duty cycle on the multimeter. The proper values are shown in table 2.

YES - The values for the duty cycle are in the appropriate range. The calibration of the joystick was successful. Perform any other calibrations of the solenoids that are necessary. Resume normal machine operation.STOP
NO - The values for the duty cycle are not in the appropriate range. Recalibration of the joystick was not successful. Repair: The joystick has an internal failure. The joystick has serviceable parts. Replace the parts that are suspected of causing the problem.STOP
