Automatic calibration of remote hydraulic valve flow

摘要

A computer calibration method and apparatus for calibrating one or more auxiliary hydraulic valves on a work vehicle includes the steps of selecting a first auxiliary hydraulic valve, applying a valve opening signal to that valve, measuring a pressure in a flow restricted signal circuit coupled to the valve, comparing the first pressure with a predetermined pressure to see if the valve is cracked open and if the valve is not cracked open, incrementing the signal to a second level and repeating the foregoing steps until the first valve cracks open. The final step is saving a value indicative of the signal at which the valve just cracked open.
