14-20 – Vibration Spectrum Survey Chapter 14 Revision 4.10, Apr 2020
Pressing the [F2] “X scale” or [F3] “Y scale” keys will change the [F1], [F2], [F3] and
[F5] boxes to read “Expand,” “Default,” “Shrink,” and “Cancel” respectively as shown in
the following figure.
Pressing the [F1] “Expand” key will expand the X or Y scale of the spectra, in
effect enlarging the viewing area. You might think of this function as a “Zoom
Out” feature. The center of the Expanded view will be the position of the cursor
prior to pressing the [F1] key. If the view is already at the maximum range of the
specified X-scale range, no scaling change will occur. However, the cursor will be
displayed and the X, Y, and “Ovr” (Overall) values will be shown in the upper
right corner of the screen. The boxes above the [F1], [F2], [F4] and [F5] keys will
return to “Options,” “Pause,” “Overall” and “Restart” respectively. If you wish to
Expand the X scale even further, retrace the steps from that point as described in
the text.
Pressing the [F2] “Default” key will return the X or Y scale to the values specified
in the setup. This is a quick and easy way to return all expanded and shrunken
scales to that default value without the necessity of numerous keystrokes. If the X
and Y scales are already at the setup values when the [F2] Default key is pressed,
the four function boxes will return to “Options,” “Pause,” “Overall” and “Restart”.
No other changes will occur.
Pressing the [F3] “Shrink” key will lower the X or Y scale of the spectra, in effect
shrinking the viewing area. You might think of this function as a “Zoom In”
feature. If the view is already at the minimum of the specified X scale range, no
scaling change will occur. However, the cursor will be displayed and the X, Y, and
“Ovr” (Overall) values will be shown in the upper right corner of the screen. The
boxes above the [F1], [F2], [F4] and [F5] keys will return to “Options,” “Pause,”
“Overall” and “Restart” respectively. If you wish to Shrink the X scale even
further, retrace the steps from that point as described in the text.
