<ENTER>
x Press <LEARN> to access the LEARN mode. The blinking LEARN-
LED indicates that the 788 IC Filtration Sample Processor is ready to
execute the command.
x Now move the lift into the desired position with the <Ð> and <Ï>
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
<ENTER> and thereby exit the LEARN mode. The LEARN LED
goes off again.

5 PUMP 1.1 : 240 s
x In this line the peristaltic pump at the 788 IC Filtration Sample Proc-
essor is started in order to convey the sample from the sample tube
to the sample loop at the 733 IC Separation Center.
x Here, you can use the LEARN mode to optimize the pump time too.
x In this case, as with the other "teachable" commands (the LIFT
command is an exception), pressing the <LEARN> key causes
immediate execution of the corresponding command. The elapsed
time is also displayed here "live". By pressing the <LEARN> key
again the command can be interrupted.
x The blinking LED indicates that the 788 IC Filtration Sample Proces-
sor is still in the LEARN mode. If you now switch the pump back on
with the <LEARN> key, you will see that the "live" value (pump time)
is now added to the existing value.
x Now set the pump time in this way. Accept the total time with
<ENTER> and exit the LEARN mode in this way.
