• Press [Add curves] in order to display a selection list of the curves in
the working memory which can be compared with each other. One or
more curves can now be selected.
• Hold down the <с с> (Shift) key and press the cursor key <é> or <ê>.
The selected curves will be marked with the ‘ь ь ’ sign and displayed when
the <ENTER> key is pressed. The same method can be used to remove
curves again.

Overlapping curves are shown in light gray except for the active curve. The
<é> and <ê> keys are used in order to select a particular curve. This
then becomes the active curve and is shown in black. The corresponding
name of the determination file is shown in the title line. Only the EPs of the
active curve are visible.
10.3 Curve presentation
The presentation of the curves of a titration or series of measurements can
be altered at a later date. All those settings are available which are possible
for the titration or measuring mode. Please note, for example, that for the
presentation of curves on the time axis or the presentation of derivative
curves in the
SET mode the necessary data must be present in the
measuring point list. The corresponding settings (Time recording,
Derivation
…) must have been used in the determination, see page
151f.
The settings for the curve display can be found in the curve window under
the softkeys [* Param][Curve display].
