4.5 Changing the Pen Trending View Display
Guardian allows the tracing view to be altered for “Limits”, “Center Origin” and “Time”. Changing the
“Time” allows either 1, 1.5 or 3 minutes of trend data to be displayed on the screen at any given time.
To change the Graph Scale, press the right mouse button and select “System” then “Graph Window
Scale” from the shortcut menus.
Guardian will display the Window Scale Parameters dialog box (shown below) where Low is the left
most Unit and High is the right most unit to frame the window.
Enter the Low and High scale values and then click on the OK button.
