4.5.2 Main Historic Tab
The main historic tab allows to define the data contained in the main time history. The main time
history graph is a useful tool when it comes to define the time boundaries to a specific portion of
the measurement.
For example, the following figure illustrates the speed in miles/h in the main time history graph.
And the main time axis boundaries are then adjusted to the measurement portion where the speed
was stable at 60 miles/h (OBSI standard) and perform averaging on this specific portion of the
measurement.
Once the measurement time boundaries are set, the measurement region of interest can be saved
using File/Save selection as.
