ERROR VOLUME SYSTEM AND METHOD FOR PUMP

摘要

PROBLEM TO BE SOLVED: To provide a system and method for reducing the error in the amount of a fluid dispensed by a pump, by correcting for the compliance of a dispense system.

SOLUTION: A method for compensating for errors in dispense volumes of the dispense pump includes: determining a dispense volume amount based on a dispense recipe; determining a value for a fluid property based on the dispense recipe; determining an error volume amount based on the value of the fluid property based on a correlation between the error volume and the fluid property that accounts for compliance in the dispense system; and controlling a dispense motor to move a piston in the dispense pump to a position to account for the dispense volume amount determined from the recipe and the error volume amount to dispense the dispense volume amount of fluid from a nozzle.
