DEF Redefining specific instrument settings
During method processing the most diverse settings can be made using
the following DEF commands. The individual entries are accessed by
repeatedly pressing the DEF key (roll-up selection).
>sample sequence
14 DOSRATE 1 160
1…12
0.01…160 ml/min
Dosing speed
The dosing speed for all 12 dosing units can be individually set. The first
parameter stands for the number of the dosing unit and the second pa-
rameter allows setting the dosing speed in ml/min.

Lift rate
The first parameter of this command defines the lift
on which the command is to be executed. Since
the 774 Oven Sample Processor is equipped only
with Lift 1, it is not practical to enter any other
value at this point.
