Metrohm Sample Processor, Introduction
can also be used to select additional functions:
- Filling the dosing or exchange unit (fill)
- Initializing the escange of a Dosing unit (release)
- Preparing the tubing systems and cylinder (prep.)
- Emptying the tubing system and the dosing cylinder (empty)
- Ejecting the cylinder contents (Eject)
- Driving the piston to the max. volume
- Compensating for the play between piston and spindle (compen.)
- Valve switching (port)
The first parameter of the DOS command stands for the number of the
dosing instrument (1…3, * = all) and the Dosino port (e. g. 1.1 stands
for Dosino 1, port 1), the second parameter for the function or the vol-
ume to be dosed.
Example:
DOS: 2.1
DOS: 2.*
The dosing and filling rates can be set in the parameter menu or with
the
1
SCAN
Shows the incoming signals or data from the Remote or the serial
RS232 interfaces.
This function is used for checking the data communication with con-
nected devices.
The first parameter shows the selected interface. The second parame-
ter shows the signals or data that are received directly.
If the parallel Remote interface (Rm) is selected then the signal states
of the incoming Remote lines are shown in binary form (1=line active,
0=line inactive).
If the serial RS232 interface (RS) is selected then the data string re-
ceived via this interface will be shown (14 characters per line).
Example (Remote interface):
SCN:Rm :00000001
In this case the Ready line (Remote line input 0) of a connected Ti-
trino is set.

CTRL
Controls external devices via the Remote or RS232 interface.
The first parameter sets the interface (). The second pa-
rameter defines the status of the lines (Remote lines) or data (RS232
interface) to be outputted via the selected interface.
2nd parameter, for Remote interface
Binary pattern with 14 digits (0, 1 or ∗) for the 14 output lines or prede-
