Abstract
A fluid dispenser calibration system includes a fluid dispenser having a plurality of nozzles, a balance having a balance surface, and a mask positioned between the fluid dispenser and the balance surface. A nozzle pitch is a distance between two adjacent nozzles. The balance measures mass of fluid dispensed from a single nozzle and measures a change in mass on the balance surface. The balance surface has a linear dimension that is greater than the nozzle pitch. The mask includes an aperture and a catch region. The aperture allows fluid dispensed from the single nozzle to impact the balance surface. The catch region catches fluid dispensed from remaining nozzles in the plurality of nozzles.
