Beschreibung
Zusammenfassung:	A method for calibrating a peristaltic pump in a medical apparatus comprises: rotating the peristaltic pump of a predetermined rotation to pump a liquid from a fluid source from a first compartment into a second compartment of a manifold assembly, raising a level of the liquid in the second compartment and compressing air in an air buffer volume of the manifold assembly; measuring a pressure of air in the air buffer volume; calculating, from the measured pressure, a variation of liquid volume in the second compartment due to the rotation of the peristaltic pump; calculating, from the variation of liquid volume and the predetermined rotation, a stroke liquid volume of the peristaltic pump.
