number of samples: rack
x The first menu entry defines the number of sample tubes (without
the special beakers) that are to be treated in a series. Here you can
choose between 'rack' (= a sample rack that is partially or com-
pletely filled, only positions with a sample tube are counted) and '*'
(= infinite number of samples) with <SELECT>. However for this
learning sequence, enter '3' on the keyboard. It is also possible
here, as with the other parameters, to enter data manually or use the
"select" choice.
