‘Sequential’ filling mode

In ‘Sequential’ filling mode, you control liquid aspiration using an aliquot list

(1 ... 10 aliquots). In this table, different volumes can be defined, which are

aspirated successively in this operating mode. Each time the STEP button is

pressed, the current volume is aspirated. The program then switches to the

next volume in the aliquot list, and this continues until all preset aliquots are

aspirated. 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 aspirated, the display moves

down the list (1, #2,  #1, 2, #3  #2, 3, #4 ... #10). The device automa-

tically switches to liquid dispensing when the desired volume or the nominal

volume is reached.
