When the list is opened for the first time you will see that it already con-
tains a window which covers the whole measured value or volume
range. You can add and edit new windows with [New]. The selected
window can be removed from the list with [Delete]. You can use
[Edit] to adapt the upper and lower limits for the selected window. All
calculable variables can also be applied as result variable R1…R9. This
means that you have to define the results in a preceding CALC com-
mand. If results are used as limits, only one window can be set then.
Windows must not overlap but may touch one another. Equivalence
point recognition criteria can be defined for each window. Please note
that no direct parameters can be defined for setting windows.
• Lower limit: Measured value or volume for the lower limit of the
window.
• Upper limit: Measured value or volume for the upper limit of the
window.
• EP criterion: The set equivalence point criterion is compared with
the ERC (Equivalence point Recognition Criterion) which has been
found. Equivalence points whose ERC is smaller than the set EP cri-
terion will not be recognized (see below). The default value is suit-
able for most titrations.
• EP recognition: Only equivalence points which fulfill particular cri-
teria will be recognized: the first (only the first EP to be found), the
greatest (only the EP with the largest ERC, i.e. the steepest jump),
