Appendix 2: Frequently Asked Questions (FAQs)  

••••

  

 80 

10) Answer “Yes” to “Would you like to initialize with 

these settings?” 
 

How should I interpret the data recorded by my 
Eagle? 

1)  See “Understanding Scanner Records” on the 

website at 

http://www.powermonitors.com/support/understandi
ng.pdf

, or on the CD included with your Eagle.  If 

that does not help, call 1-800-296-4120. 
 

How do I import older WinScan data files for use 
with ProVision? 

1)  In ProVision, select [File] then [Import]
2)  Locate and select the folder containing your 

WinScan data files. 

3)  Answer “Yes” to “Should the folder be added 

recursively?” 

4)  The WinScan data files should now be displayed in 

the explorer tree in the under the “Imported Files” 
folder. 
 

How do I change the scaling (upper or lower 
bounds) on a graph? 

1)  While looking at a graph, select [Tools] and then 

[Upper/Lower Bounds]

2)  In the “Upper/Lower Bounds” window, select 

“Manual Scaling.” 

3)  You can now change the upper and lower bounds 

to values of your choice.  If you would like to set the 
bounds to all plots, simply click [Set all scales to 
this scale]
 after typing in your desired bounds.
