sured. The correction weight required is determined by Equation
(6.2).
Correction Weight = Trial Weight × O/T (6.2)
The angle formed by the T vector is the location of the cor-
rection weight. This process can be repeated as often as required
until acceptable results are obtained. Generally, two balancing
runs should provide good results. As with all maintenance prac-
tices, careful attention to small details will result in big divi-
dends.
