(positive) volume and filling the cylinder are also possible with 685 and
805 Dosimats.
If * is entered as wild card for the drive then the selected function will
be carried out by all the connected dosing devices.
If * is entered as wild card for the port then the particular function will
be carried out at the port defined as standard in the parameter menu
under >def. Dosing units . This means that this setting is method-
specific, but also applies to manual operation depending on the loaded
method.
Dosing
DOS: X.Y : xxx.xx mL Adds a particular volume
The given volume will be ejected though the selected port. If a value
with a negative sign is entered then the volume will be aspirated.
The Dosing unit will not be refilled after each addition. The standard
dosing port (Port *) is that defined under
>dosing drive X
dosing port Y
(default: Port 1).
Filling
DOS: X.Y : fill mL Fills the cylinder
The Dosing unit is filled completely. The liquid is aspirated via the given
port. The standard filling port (Port *) is that defined under
>dosing drive X
filling port Y
(default: Port 2).
Prepare
DOS: X.Y : prepar. mL Prepares = rinses and fills the
connected tubing and the dos-
ing cylinder
The tubing system of the Dosino should be freed from air bubbles at
least once per day by carrying out a preparation cycle. This is a process
that could take some time.
It is recommended to use this command in a start sequence.
