At this point, you can choose how to place a trial weight on Plane one. Either
Add or Cut. If you are adding weight, you are physically attaching a weight to the
rotor. If you are removing weight, you are physically removing the weight from a
rotor. This could be removing a set screw or by
drilling a hole.
Method
: Select Add or Cut
Trial Mass
: Enter the weight of the trial mass.
It is recommended that your trial weight will
effectively cause at least a 30% change in
vibration amplitude or 30 degree change in
vibration phase. Failure to have sufficient
change will generate inaccurate balancing
coefficients. Likewise, it is recommended to be
careful not to put too much trial weight to
