ABSTRACT:
Determining a shaft balance adjustment includes measuring an initial vibration of the shaft, determining if the initial vibration is greater than a predetermined value, and, if the initial vibration is greater than the predetermined value, determining an adjustment by choosing a best adjustment for each possible location for adjustments. Choosing the best adjustment may include choosing an adjustment that causes a lower amount of vibration than adjustments not chosen. Measuring an initial vibration may include using an accelerometer. Measuring an initial vibration may include using conditioning electronics in connection with the accelerometer. The predetermined value may be 0.01 ips.
