Selection whether the calibration is to be done with
quantity unit ml ( µl ) or g (mg) * and confirm this, the set
quantity
can be set as desired.
* If the saved density value corresponds to the value
1.000 g/cm³ (default value), the input dialog for the
material density appears when you select g (mg) . See 5.9.5,

• Set and confirm the set quantity.
The value of 0.5 ml preset in the Dosing system is to be regarded as the ideal value.
• Position the calibration vessel underneath the outlet nozzle (dosing needle) of the

previously set measuring unit. See also 5.9.1, Dosing amount.
• Input and confirm the ACTUAL quantity that has been determined.
• Select the OK button and confirm, the next dialog to save the calibration value

5.8.2 Calibration manual
The Calibration manual function provides a simplified option to recalibrate the system
without having to run through the entire process in the Calibration auto menu.
This can be helpful, for example, after changing the stator, in the event of batch-
related product variations, etc., whereby the set dosing value is not to be changed
(QA documents, etc.).
Caution: Setting the flow rate in the Calibration manual menu also changes the
dosing results of all the dosing programs by a linear factor.
