    Abstract: A method of calibrating the jetting profile includes applying voltage to a piezoelectric actuator (34) to move a valve closure structure (18) between non-impact and impact positions, sensing the position of the valve closure structure, establishing a reference point using voltage and position data, and using the reference point to adjust the voltage applied. Another method uses a mechanical stop to calibrate a jetting system. This method includes applying voltage to the piezoelectric actuator to move the valve closure structure between non-impact and impact calibration positions, sensing the position of the valve closure structure, generating voltage and position calibration data, establishing a master reference point using this data, and using the master reference point to determine wear of at least one of: the piezoelectric actuator and the valve closure structure. Another method of operating a jetting system includes the user inputting information into a control component. Another method involves using voltage data and the position data relating to a piezoelectric actuator for preventative maintenance of one or more components of the jetting valve.
