The port assignments of a 700 Dosino can be changed as needed.
The first parameter stands for the dosing unit and inlet or outlet
port of the Dosino. The dosing unit and the port must be separa-
ted by a period. The four ports (1–4) of every 700 Dosino can the-
refore each be designated a function.
The second parameter determines the function of the associated
port.
dos. : Dosing occurs via the corresponding port.
fill : Filling always from the corresponding port.
rinse : Before changing the dosing unit the burette will be fil-
led from this port.
prep. : Tubings will be emptied via this port during a prepara-
tion cycle. The rinsing volume will be aspirated from
the filling port.
drain : During emptying air will be aspirated via this port. The
liquid is ejected via the dosing port.
If the dosing device connected is a 685 Dosimat , the port as-
signments will be ignored.
