This statement has a certain degree of one-sidedness, but it does make some sense because the larger the mass range of the automatic positioning dynamic balancing machine, the greater the measurable rotor mass. However, it is not necessarily that the larger the mass range, the more specifications the measured rotor will have. If the measured rotor mass is too small, it will cause it to be out of sync with the power system, not only increasing power costs but also affecting the service life of the power system, So when choosing, everyone should choose the quality range of the dynamic balancing machine according to their needs, rather than blindly pursuing a large quality range.
