Calibration canbe used to set the pump flow to the actual operatingconditions.Calibrate the pump under normal operatingconditions with the discharge line connected and atoperating counter-pressure.NoteThe dosed volume must be gauged inlitres during calibration, e.g. by drawingthe dosing medium from a gauged tank.(For an alternative for pumps with Plus 3system, see section 9.6.1 Calibratingpumps with Plus 3 system (internalcalibration)).NoteDue to the small stroke volume of theDDI 0.4-10, calibration is essential fora precise dosing flow.Before calibrating the DDI 0.4-10,deaerate the pump and then let it runfor 15 minutes at operating counterpressurewith full stroke rate.41
