Procedure for equilibration of the delivery volumes of a multi-channel metering apparatus with an arrangement of independently controlled dispensing channels-.n, delivering individual volumes of dispensing fluid to cavities-.n.n, where measured values relevant to the individual delivery volumes are measured for the same control value and from which an adjustment value is specified with a tolerance band and the control value is adjusted for dispensing channels-.n, the measured values of which lie outside the tolerance band. The invention also applies to an apparatus for implementing the procedure.

Procedure for channel adjustment of a multi-channel metering apparatus

Multi-channel metering apparatus with automatic calibration, where the individual dispensing channels, the micro-valvesof which are connected with the outlets of a distributororwhose inlet is filled with fluid by a vesselorthus connected, are able to be calibrated in relation to each other in that between the vesselorand the inlet of the distributorora flow sensoris arranged which for calibration during delivery of the fluid via a respective nozzleof a respective dispensing channelrecords the flow and generates signals which are respectively assigned to a defined opening time of a micro-valveand a specific dispensing channeland thus stored allows for individual control of the micro-valvesin order to equalize the tolerances of the dispensing channels
