plane balancing, repeat this step if you want the instrument
to recommend trial weight placement angles for both planes.
After you take the initial reading the instrument will display the
suggested trial weight angle in the upper right of the screen.
Notes:
Angles are measured in the direction you designate as your Weight
Orientation i.e. with rotation or against rotation.
If you are performing a dual plane balance you should only use this
option in cases where each balance plane is physically close to its
sensor, and the two planes are separated from each other by a
distance greater than the rotor diameter. In particular for overhung
rotors this option should only be used for single plane balancing on
the closest bearing and balance plane, to help with reducing the
static imbalance only. The CH2 or CH4 sensor and weight reference
mark must be in line with those of CH1 or CH3.
