Set flow rate
The contact pressure of the tubing cartridge must be adjusted in order to
regulate the flow rate. Proceed as follows:
Set the contact pressure
1
￭
Fully loosen the contact pressure lever (6- 5 ) , i.e. press it all the
way down.
￭
Switch on the peristaltic pump.
￭
Raise the contact pressure lever one step at a time until liquid
flows.
￭
When liquid starts flowing, raise the contact pressure lever by an
additional 2 ratchet increments.
The contact pressure is now set optimally.
The delivery rate depends not only on the correct contact pressure
but also on the interior diameter of the pump tubing and the rota-
tional speed of the drive.
