Instruction Manual
Opening a recording and choosing a selection
When opening an RPM recording the RPM indication will be
shown at the bottom of the screen. To be able to see where
the RPM indicator shows a section of constant increasing
RPM, it may be wise to zoom the video out by using the
zoom slider on the lower right of the screen
For further analysis it is possible to use the entire recording,
or to make specific selection of the recording by selecting
the part of the video of the bottom of the screen which is
desirable. The selection should be from the part where the
RPM indicator shows a constant increasing (or decreasing)
RPM. Note that a selection has to be at least 5 seconds
long to conduct further investigations by order analysis. A
different selection may be made by highlighting a different
part of the video. The selection may also be removed by
pressing the “Clear current selection” button.
Place the virtual microphone on the area of interest for
further analysis.
