ZOOM IN / ZOOM OUT SCREEN VIEW
You can look at the graph lines in greater detail when you zoom in on the graph. A typical graph screen will have grid
lines that are spaced at one second intervals. It is possible to zoom in to the point where these grid lines are as small as
1/100th of a second intervals, revealing much more detail than what can be seen on the bigger screen. There are two methods
of doing this.
ZOOMING IN USING THE PLUS (+) AND MINUS (-) ICONS
Step 1:
With the run file displayed on your screen, point the arrow screen cursor at the item on the screen you wish to
enlarge.
Left click to move the vertical cursor to this location
.
Step 2: Click on the Zoom In icon
on the toolbar. The screen will become slightly enlarged.
Step 3: Repeatedly click on the Zoom In icon
until the magnification has increased to show the detail you want.
When you are through looking at the zoomed in screen you can reduce the magnification in steps by repeatedly
clicking on the Zoom Out icon just below the Zoom In, or you can return to the original screen size in one step by clicking on the
User Scale icon, the yellow box with a red squiggly line and an X and an O on either side of it.
ZOOMING IN USING THE MOUSE
A second, and quicker method of zooming in on a portion of the screen is to draw a box around the area of interest
with your mouse. This method will magnify the area within the box to full screen view in one step.
Step 1:
With the run file displayed on your screen, locate the area you want to enlarge.
Step 2:
With your mouse,
move the arrow cursor to the upper left of the area you want to enlarge
.
Depress and
hold the right mouse button down and slowly move the cursor toward the lower right of your graph
. A box will
appear on the screen. Stop and then
release the mouse button
when you have defined the area you want to view.
The area within the box will be magnified to full screen view.
Step 3:
This enlarged view will not contain the vertical cursor unless the box you drew covered a portion of the cursor.
To insert the vertical cursor in the enlarged screen move the mouse arrow onto the portion of the screen you want it
to be located and left click.
To reduce the screen to it’s original size you can use the same methods as outlined above by using the plus and
minus icons or the User Scale icon.
ZOOMING OUT
There will be occasions where you may want to zoom out to see a greater portion of the recording than displayed in
the normal screen view. You might even want to view the whole recording period on one compressed screen.
This can be
accomplished in the same manner as you used for zooming in, but using either the Zoom Out or the Autoscale icons
.
When using the Autoscale icon it isn’t necessary to right click and draw a box. The screen will automatically display the entire
recording period as soon as you click on the Autoscale icon.
