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 Dos-
ino. The dosing unit and the port must be separated by a period. The four
ports (1-4) of every 700 Dosino can therefore each be designated a func-
tion.
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 filled from
this port
prep : Tubing will be filled from this port during a preparation cycle.
The rinsing volume will be ejected via the dosing port.
empty : 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 assignments will
be ignored.
