Inspection and Measurement
Inspection point: Incline motor and VR calibration
Inspection method: I. Calibration goals
Adjust the incline set tube to the red calibration line. Adjust the VR voltage across red
and green wires to 1.20V.
II. Calibration steps:
Step 1. Adjust the incline tube to the red calibration line as follows:
A. Remove VR set screws. Remove the VR cap.
B. Rotate the VR to set voltage across red and green wires to 2.5V.
C. Press the INCLINE<

tube return to the red calibration line.
Step 2. Adjust the VR voltage across red and green wires to 1.20V.
A. Rotate the VR to set voltage across red and green wires to 1.20V.
B. Use screws to secure the VR cap back into place.
Step 3. When calibration is complete, test incline operation as follows.
A. Press the Incline<
