Claim Text:
1. A method of calibrating an electronically actuatable hydraulic valve, the method comprising: providing at least one supply valve and at least one drain valve to be calibrated in fluid communication with one another, the at least one supply valve configured to supply hydraulic fluid from a fluid source to at least one hydraulic cylinder via a pump and the at least one drain valve configured to drain hydraulic fluid from the at least one hydraulic cylinder to the fluid source; providing a bypass valve in fluid communication with the pump and the fluid source; opening the at least one supply valve and the at least one drain valve; closing the bypass valve; setting the pump to a desired flow output; determining a first current command for the at least one supply valve corresponding to a first target pressure parameter; and determining a second current command for the at least one drain valve corresponding to a second target pressure parameter.
