9.6 Calibration
The dosing flow display is set by default for an
operating counter-pressure of 3 bar. Calibration can
be used to set the pump flow to the actual operating
conditions.
Calibrate the pump under normal operating
conditions with the discharge line connected and at
operating counter-pressure.

Note
Due to the small stroke volume of the
DDI 0.4-10, calibration is essential for
a precise dosing flow.
Before calibrating the DDI 0.4-10,
deaerate the pump and then let it run
for 15 minutes at operating
counter-pressure with full stroke rate.
Note
The dosed volume must be gauged in
litres during calibration, e.g. by
drawing the dosing medium from a
gauged tank. (For an alternative for
pumps with Plus
3
system, see section
9.6.1 Calibrating pumps with Plus
3
system (internal calibration)).
