13.6 Trace function
Fig. 13-12 Menu: Scaling of graphics
If a marker is active, pressing the soft key 2nd marker will display a 2nd line in
the diagram. These two lines define the range that you can then have displayed
over the entire display range by pressing soft key Zoom.
The process of zooming a range (marker ON, 2nd marker, zoom) can be re-
peated as often as desired until the maximum size of representation is reached.
Use the soft key Fullscreen to switch the display of the diagrams back to their
X and Y markers can be active at a time.
Use the soft key Scale to change the scaling of the traces and of the marker
ranges in the two graphs.
The scaling can be switched over between auto (default setting) and fixed. The
Y range (Y min/max) to be displayed can only be changed in fixed mode.
