If the calibration is not correct, there will be phase mismatch, which is manifested as: the dynamic balance detected by the machine is at 135 degrees, but it is not actually at this position. There may also be errors in the dynamic balance value. If the detected quantity is 2g, it may actually only be below 1g or above 3g.
Calibration is very important for balancing machines during rotor dynamic balance testing. A qualified balancing machine is useless if not calibrated. Before the first inspection, a computer balancing machine must be calibrated. This can help the machine accurately correct the accompanying or angle of dynamic balance, which refers to determining the position of the rotating workpiece's dynamic balance.
