Noise and vibration during running
Please check the balanced status of both the table and the instrument.
Please re-check the coupling status of the following three matches to minimize the
noise
1. the balanced way of coupling of the rotor into the motor shaft
2. the completeness of fixing of the Rotor Locking Nut on the rotor
3. the matching status of Rotor Lid with the rotor
(Please refer to 3-2. Rotor Coupling and Disassembling)
Check balances of samples in the rotor. (Please refer to 3-3. Positioning of Sample
Tubes) and load the same weight of samples symmetrically.
