PURPOSE:To make display easy to observe and to make it possible to simply and accurately perform balancing work, by correcting the display position of imbalance to the actual imbalance position of a rotor by a correction means. CONSTITUTION:At first, the vibration generated by the imbalance of rotors 3, 4 is detected by a vibration detection means (acceleration pickup) 7. Next, the origin positions of the rotors 3, 4 are detected by an origin detection sensor 10. Subsequently, the quantities of deflection at every plural indexing positions based on the origin positions are respectively operated on the basis of the signal from the acceleration pickup 7 by a control means (CPU)24. Next, the indexing position corresponding to the max. value of deflection quantity operation values is selected by CPU24 and the selected indexing position is corrected on the basis of a phase variation value by a correction means (position controller) 21 and the display body 14 corresponding to the corrected indexing position is displayed on a display device 12 by CPU24. |
