3.2.2 Defining dosing units
In order for the complete tubing system of a Dosino to be fully filled with the
reagent solution without any air bubbles the 711 Liquino must know the di-
mensions of the connected tubing. For this reason a dosing unit can be de-
fined in the configuration menu and then selected for the method.

Except for the "Sampling dosing unit" in the SMPL mode the standard port
occupancy for all modes is as follows:
Port 1: dosing unit output

In a single method ‘standard’ can also be selected for the dosing unit used. For the modes XDOS, CONT
and GLP ‘standard’ means:
Port1 (dosing port): L = 40cm, D = 2mm
Port2 (bottle): L = 25cm, D = 2mm.
For PIP ‘standard’ means: Port1 (pipetting tubing): L = 150cm, D = 2mm
Port2 (bottle): L = 25cm, D = 2mm.
For SMPL ‘standard’ means: Port1 (sample tubing): L = 40cm, D = 2mm
Port2 (measuring cell): L = 16cm, D = 2mm
Port3 (rinsing agent): L = 50cm, D = 2mm.
