3.20.6 Live parameters
Certain method parameters can be edited while a determination is
being carried out.
Open the Edit parameter dialog while a determination is currently
being carried out.
The [Edit command] button is active for a command in which live
parameters can be edited. The sequence, i.e. the sequence of
commands, cannot be altered. This is why the [Delete command] and
[Insert command] buttons are inactive. Under Method options all
functions are accessible except the method properties. The method
cannot be saved while a determination is being carried out.
As an example, open the dialog for editing the Start conditions
for a DET titration.
Only parameters which it is possible to edit while a determination is
being carried out can be edited.
