VIBXPERT Balancing 11.2010
Appendix
Pointer change too large
The vibration pointer in the trial run has changed too much in
magnitude and phase in comparison to the initial imbalance run.
Pointer change too small
The vibration pointer in the trial run has not changed enough in
magnitude and phase in comparison to the initial imbalance run.
If the change is too large, the trial weight must be reduced. If it is too
small, the trial weight must be increased.
Restart is recommended (1-plane balancing)
If the vibration values increase and the balancing weights increase
from one balancing run to the next, no further improvement can be
expected. The entire balance measurement must be restarted.
Masses combined.
Remove previously attached masses!
The previously attached balancing weights are added together
(vectorially) to form a single weight. Attach the weight calculated in
the data screen to the rotor, and remove all previously attached
balancing weights. Start the next balancing run. In comparison to the
last run, the balanced state should not change substantially.
