PDA Graph
Previous Topic  Next Topic 

> While in any of the “View” screens select the “Graph” button.

 

Graphs are available for both Travel vs. Time and Velocity vs. Time.

 

 - Be Patient - It is a PDA after all. When the Graphs are drawing wait until they are finished. If you start tapping on the OK button or some other tab it will stack up commands.


> Travel Graph 

While in any of the “View” screens tap the “Graph” button.

 

This screen displays Travel vs. Time in 30 second increments in millimeters (mm).  To view the next 30 seconds tap the “toggle button” to the right.  

 

The Travel Graph also displays Adjusted Average Travel, Peak Travel and Average Peak Travel in millimeters (mm).

 

 - Zoom In!

 - Drag a window around the portion of the graph you want to zoom in on.  To switch back to the original view tap “Zoom Reset”.


> Velocity Graph 

While in any of the “View” screens tap the “Graph” button.  Tap the “Velocity” tab.

 

This screen displays Velocity vs. Time in 30 second increments in Meters per Second (M/s).  To view the next 30 seconds tap the “toggle button” to the right.  

 

On the Velocity Graph, Compression is displayed above zero while Rebound is below zero.

The Velocity Graph also displays Average and Peak Average Compression and Rebound Velocity in Meters per Second (M/s). 

 

 - Zoom In!

 - Drag a window around the portion of the graph you want to zoom in on.  To switch back to the original view tap “Zoom Reset”.
