12.1 Sequential Dispensing in detail

In Sequential Dispensing operating mode, you dispense a defined sequence of different or equal vol-
umes of liquid. These volumes are called aliquots and are defined via the aliquot list (1 ... 10 aliquots).
In the operating mode, you then see up to 3 entries of the aliqout list. These entries – specifically, the
previous, current and next entry – are indicated by a number sign (#). If an aliquot is dispensed, the
display moves down the list (1, #2,
ficient volume has been aspirated.
If the aliquot amount exceeds the tip volume, you can aspirate liquid again and then continue dis-
pensing.
If the aliquot amount is less than the tip volume, enough liquid is aspirated as is needed for the given
aliquot list.
If you cancel an aliquot (X button on the display), this aliquot is counted as not dispensed. In this case,
an event message is output. The program jumps to the next aliquot in the list. If there is not enough
liquid in the tip at the end of aliquoting, the device aspirates exactly the required amount of liquid, in
order to complete aliquoting.
The aliquot list can no longer be changed when the first aliquot has been dispensed. You can edit the
aliquot list again only after you have completed dispensing.
