• Now move the lift into the desired position with the <ê> and <é>
keys. You will notice that the current lift position is always indicated
"live". During execution of the command the LEARN-LED is lit con-
tinuously. Accept the lift position that has been set by pressing
and thereby exit the LEARN mode. The LEARN LED
goes off again.

4 CTL:Rm: FILL A 1
• In this line the injection valve at the 733 IC Separation Center is
switched to the "Fill" position.

5 PUMP 1.1 : 120 s
• In this line the peristaltic pump at the 766 IC Sample Processor is
started in order to convey the sample from the sample tube to the
sample loop at the 733 IC Separation Center.
• Here, you can use the LEARN mode to optimize the pump time too.
• In this case, as with the other "teachable" commands (the LIFT
command is an exception), pressing the key causes
immediate execution of the corresponding command. The elapsed
time is also displayed here "live". By pressing the key
again the command can be interrupted.
• The blinking LED indicates that the IC Sample Processor is still in the
LEARN mode. If you now switch the pump back on with the
key, you will see that the "live" value (pump time) is now
added to the existing value.
• Now set the pump time in this way. Accept the total time with
and exit the LEARN mode in this way.

6 CTL:Rm: ZERO 1
• In this line the autozero function at the 732 IC Detector is triggered.
>sample sequence
7 CTL:Rm: INJECT A 1
• In this line the injection valve at the 733 IC Separation Center is
switched to the "Inject" position.

8 WAIT 1200 s
• In this line a waiting time is defined that is used for the acquisition of
the chromatogram.
• The LEARN mode can also be used with the WAIT command.
