CALIBRATION METHOD FOR IMBALANCE MEASUREMENT DEVICE AND ITS DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a calibration method for an imbalance measurement device capable of providing an improved calibration result. SOLUTION: Two calibration masses equivalent to or different from each other are simultaneously rotated around measurement axes on two axial planes during a calibration process, force generated by imbalance caused by the calibration masses is measured, and the calibration of the imbalance measurement device is evaluated with respect to the measured force.
