Beschreibung
Zusammenfassung:	A method for removing the effects of slack in a syringe pump having a syringe loaded on the syringe pump, the syringe having a barrel and a plunger disposed within the barrel, the method comprising receiving a target flow rate of the syringe loaded on the syringe pump, determining a therapy actuation speed corresponding to the target flow rate, actuating the plunger of the syringe out of the barrel at a first predetermined speed until a force sensor coupled to the plunger measures a force that is less than a first predetermined force threshold, actuating the plunger of the syringe into the barrel at a second predetermined speed greater than the therapy actuation speed until the force sensor coupled to the plunger measures a force that exceeds a second predetermined threshold, and actuating the plunger of the syringe into the barrel at the therapy actuation speed.
