value) are displayed in the graphics window next to the measurement
curve (green).
With the button [Evaluation] you can display the second derivative of
the measuring curve as well as the used evaluation sensitivity.
Zooming graphs, switching on/off offset and autoscaling
Proceed as follows to adjust the graph display:
1 Zoom graph
￭ See "Zooming", page 31.
2 Switch on/off offset for multiple curves
￭ Right click in the dialog window of a multiple graph.
The context-sensitive menu for graphs appears.
￭ Click on the menu item Offset.
The offset for the displayed measurement curve is switched on or
switched off.
In the case of an activated offset, the curves are arranged with an offset
above one another. Instead of the usual lettering of the conductivity
axis, the difference of the entire axis is in this case displayed in µS/cm.
3 Switch on/off autoscaling for single and live graphs
￭ Right click in the dialog window of a single graph or live graph.
The context-sensitive menu for graphs appears.
￭ Click on the menu item Autoscaling.
The autoscaling for the displayed measurement curves is now activated
or the manually performed scaling (see Chapter 4.5.2.3, page 67) is
canceled.
If this option is activated, the start and end values of the axes are auto-
matically specified in such a way that all measured values are visible.
