Fig. 14.

Homing procedure and reliability measurement. A syringe has been placed on the system and homed. The blue arrows represent the homing procedure that consists of pulling then pushing the pusher after triggering the limit switch. The green arrow represents the arbitrary injection that reflects the typical use of the pump; a large volume up to the complete injection of the syringe or the successive injection of small volumes. The distance “d” has been measured after each cycle. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
