5. Select the "Y mode" to define "Absolute" or "Relative" y-axis values.
6. Define the "Y start" and "Y stop" values that define the lower and upper borders
(respectively) of the zoom area on the y-axis.
When you close the dialog box, the specified area is magnified in a new zoom dia-
gram. The original diagram is displayed with the zoom area indicated as a rectan-
gle (see Figure 7-3).
To define the zoom area numerically using position and range values
1. On the "Menu" menu, tap "Horizontal".
2. In the "Zoom" tab, select "Position/Range".
3. Select "X mode" to define "Absolute" or "Relative" x-axis values. Relative values
cause the zoom area to adapt to the input values dynamically.
4. Under "X position", define the x-value of the center point of the zoom area (see
Figure 7-2).
5. Under "X range", define the width of the zoom area.
6. Select the "Y mode" to define "Absolute" or "Relative" y-axis values.
7. Under "Y position", define the y-value of the center point of the zoom area.
8. Under "Y range", define the height of the zoom area.
When you close the dialog box, the specified area is magnified in a new zoom dia-
gram. The original diagram is displayed with the zoom area indicated as a rectan-
gle.
To define multiple zoom areas
You can define more than one zoom area for the same diagram, for example to com-
pare several peaks in a measurement. These zoom areas can be displayed in sepa-
rate zoom diagrams, or together in one zoom diagram.
To define multiple zoom areas graphically, simply repeat the steps described in To
define the zoom area graphically on the touchscreen - for each area. Numerically, pro-
ceed as follows:
1. On the "Menu" menu, tap "Horizontal".
2. Select the "Zoom" tab.
3. Select the required tab according to the method you want to use to define the
zoom area.
4. To copy the current zoom area definition, tap the "Copy" icon.
Alternatively, tap the "Add" icon to add a new zoom area.
5. Enter a name for the new zoom diagram using the displayed on-screen keyboard.
6. Define the zoom area as described for the first zoom.
