Zero Point Calibration
The "Zero Point" is the programmed point to which the 5th Wheel will return whenever the auto-level
feature is used. The Zero Point is preset at the factory and should never have to be reset. However, if
necessary, Zero Point can be reset.
Note:
The Zero Point must be programmed prior to using the auto-level feature to ensure the proper
operation of the system. Prior to starting the Zero Point Calibration procedure, check all connections
on the controller, valve coils, landing gear, leveling jacks and touchpad.
