Section 9: Balancing Rotors
137
Perform Trim Balance
Used to take a measurement of the machine after the weight has
been added or removed from the rotor.
Perform Trim Balance confirms the balance level achieved after the
weights were positioned. After another measurement is taken, the
Balance Menu will display the new balancing requirements.
The balance process can end at this point or continue with another
reposition of balance weights, as indicated, to improve on the
balance level. Repeat until you are satisfied with the results or no
further reduction of imbalance can be achieved.
The ISO 1940 limits option, available from the Balance Weight
Calculations Menu, is provided with the instrument to help you
determine the acceptable level of residual imbalance for your rotor.
See Balance Weight Calculations (page
138), for more information.
Enter Trim Readings
Allows for trim reading to be manually input without having to use the
instrument to record the measurement directly from the machine.
