You may decide what to do next. If the tolerance limit was exceeded VM-BAL will suggest to continue balancing. However, you can always finish the procedure.

Result

 
6. Result
 
The result is shown as magnitude and angle according to the balancing aim.
The angle corresponds to the measured unbalance. If the balancing aim was a reduction of vibrations the angle may differ from the angle measured vibration display because of dynamic rotor properties. To maintain concurrence with the angles used during unbalance correction the unbalance angle is here also used for vibration indication.
