Abstract
A calibration system for use on a work machine wherein electro hydraulic controls are utilized to control the operation of a particular work element, the present calibration system being operable in both a semi-automatic mode and an automatic mode. In the semi-automatic mode, operator interaction is required and the calibration process is preferably initialized and controlled via a service tool which is in communication with a work machine controller. A command signal having a command signal value indicative of a command state of the component being calibrated is generated by a command signal generator, and a detector in communication with the component receives the component signal and detects when the component has reached the command state, and generates a detector signal having a value representing a calibration factor to be used in correlating the component signal value with the actual state of the component. In the automatic mode, no operator interaction is required and the controller automatically and dynamically correlates and compares the current state of the particular component being calibrated with its last stored state and thereafter calibrates the component upon detec…
