<DIN> confirms the dilution series referred to in the DIN
standard, while <2> confirms the simple geometrical
series. <ok> indicates that the current setting should be
adopted.
The unit for the sample concentration is specified here.
For environmental samples of unknown composition, e.g.
waste water, <%> should be confirmed.
In this case the current setting can be adopted with <ok>
or a new value, corresponding to the concentration of the
original sample without preliminary dilution, can be
entered with the numeric keyboard. For example, for the
analysis of waste water you can enter 100 here.
In this case <ok> indicates that the current setting should
be adopted. Otherwise a new value can be entered with
the numeric keyboard, e.g. 5, 15 and 30 minutes. If <0> is
entered as the incubation time 2, incubation time 3 is not
requested. Take account of the speed with which you
work and, depending on the length of the dilution series,
do not set incubation time 1 to too small a value.
