Balancing
Depending on your instrument, you can analyze and correct rotating
mass imbalance problems where they occur. A rigid rotor can be
balanced in one or two planes. To address a balancing problem where it
occurs:
1. Take an initial measurement of the imbalance.
2. Attach a trial weight to the balancing plane.
3. Take another measurement.
TIP: For dual-plane balancing, do the same for the second plane.
4. Attach correction weights to the balancing planes as recommended
by your instrument.
5. Take a measurement in each plane to confirm the rotor is balanced.
NOTE: You can use Trim Balancing to remove any residual
imbalance.
TIP: You can swap the display so that the rotation shown on the
screen matches the rotation of the shaft you are looking at.
