Runout Compensation
Runout Compensation Tab
The Runout Compensation Tab is used to find compensated amplitude and phase. The tab uses vector
subtraction; and subtracts the runout measured at low speed from the runout measured at balancing speed.
Runout must be compensated for prior to balancing.
This calculation can also be used to determine the actual amount of vibration that is present in the system.
To make the calculation simply enter the amplitude and phase for balancing speed (V1) and then enter the
values for slow roll (V2). Compensated amplitude and phase (V3) are calculated after each data entry.
V1 - V2 = V3
V1 equals the uncompensated amplitude and phase for balancing speed.
V2 equals the amplitude and phase for slow roll.
V3 equals the compensated amplitude and phase.
