Central View Area
The Central View area contains the screens required for a particular measurement, such as bar
graphs, result readouts and various frequently used setup parameters (that is,
Meas. mode ). The
template defines the content of this area. More than one screen can be used for displaying the
information. Select the screen using the View Tabs at the bottom of the View area.
Changes made to the screens will only be applied temporarily, that is, until you select another
project template or open another project to re-use the screen from that project. However, if you
want the screen changes to be saved in the current template, select the
Save Template option
from the Main Menu .
Note: If you make changes to the screen that you do not want to keep (and you have not yet
selected Save Template ), you can undo them by selecting the template again from the Project
Template bar at the top of the screen.
