Patent ID: 7553452

Claim:
A process for adjusting the fluid delivery volumes of a multi-channel metering apparatus with an arrangement of independently controlled dispensing channels 1 . 1 - 1 .n delivering individual volumes of dispensing fluid to cavities 3 . 1 . 1 - 3 .n.n, the process comprising the following procedural steps: delivering individual volumes of dispensing fluid via dispensing channels 1 . 1 - 1 .n, where the delivery is controlled by a control value that is the same for all the dispensing channels; measuring a value relevant to the individual volumes delivered; correlating the measurement values with the control value and the particular dispensing channel 1 . 1 - 1 .n; statistically determining an equilibration value from all the measurement values; determining a permissible band of tolerance for the equilibration value; adjusting up or down the control value of any dispensing channel whose measurement value is above or below the band of tolerance for the equilibration value; memorizing control values and measurement values as data storage groups.
