Assuming the required polar points have been captured, simply enter the
points' row numbers into the appropriate input fields and the Deg and IPS
values will be automatically filled out. Once the row numbers have been
entered, the resulting solutions are shown below the table in the same format
(ANGLE × SCALE) as shown on the propeller mode polar chart. There are two
solutions, one for each correction plane.
Here is the two plane balancing dialog that has all 6 point row numbers entered
into it and is therefore displaying solutions.
Fig 9.3. Two plane balancing dialog
The plane 1 solution is -50° × 1.18 which says attach a mass that is 1.18 times
the trial mass in a position that is 50° backwards (against the direction of
rotation) from the position where the plane 1 trial mass was attached.
The plane 2 solution is +82° × 1.14 which says attach a mass that is 1.14
times the trial mass in a position which is 82° forwards (in the direction of
rotation) from the position where the plane 2 trial mass was attached.
Use the browser back button (or ESC key) when you want to leave the two
plane balancing dialog. The data values entered are persistent so you can
leave the dialog and return to it and the values will still be there. A button is
provided to clear all of the points which is a good idea when starting a new
calculation.
9.3. Balancing procedures
Two plane balancing may be carried out using either a single accelerometer
or dual accelerometers. When using a single accelerometer, 6 runs are required
