Polar graphics

Vibration and unbalance are displayed for both planes as polar graphics. The length of the pointer indicates the amount and the angle the position. There are some options concerning the polar graphics display.

Position of zero angle

1. Position of zero angle
By mathematical definition zero position is on the right side of the circle. You may change the zero position if desired.

Angle count direction

2. Angle count direction
By definition angles are measured counterclockwise. This can be changed to clockwise.
The setting only affects the diagram. The angles at the rotor are always counted against the direction of rotation.

Fixed position counting

3. Fixed position counting
  • Fixed positions (if selected in rotor settings) can be counted. The counting start can be set arbitrarily in VM-BAL.
