Chapter 3. Polar Tab - Rotor Balancing
The polar tab shows the polar chart we use when balancing. Some features
of this tab differ depending on whether we are balancing a propeller or a rotor.
Here we see the polar tab displaying the results of a rotor balancing job.
Fig 3.1. Polar tab - rotor balancing (with options visible)
3.1. Polar chart
The polar chart shows the points that were captured during the balancing
process. The chart may be panned and zoomed 1 . If the PB-4 is connected and
the Update checkbox is checked, the chart will be updated in real-time to show
the current balance condition.
The chart may show move lines (the red, green and blue lines in the above
figure).
The current point is simply the most recent point sent from the PB-4 when the
display is being updated in real-time or the point that has been selected in the
points list when the display is not being updated in real-time.
Each point is plotted as a circle 2 , the colour coding of the plotted points are:
Point captured from axis 1. White
Point captured from axis 2. Grey
The current axis 1 point. Yellow
1 Pinch-zooming is supported for touch screens and mouse-wheel zooming for laptops, etc.
2 Other symbols (square, triangle and rhombus) are available. By default, X and X2 axis points are plotted as
circles and Y and Y2 axis points are plotted as squares.
