Chapter 2 Balancing Extension Module
The data collector takes vibration readings, calculates new trim weight(s)
and displays the values.
• If the rotor is still out of balance, repeat adding the trim weight and
taking residual measurements until the rotor is properly balanced.
• If several trim correction runs have been performed (resulting in several
trim weights), values may be combined into one permanent trim
weight.
• If the balance never improves, check to see if you entered the correct
trial weight size and location, or check other factors such as
misalignment or a faulty bearing.
However, if the vibration has been reduced to an acceptable level,
balancing is complete.
