Conclusion
Following installation and tuning of the DVIA-ML1000 (S/N 260517R3) at the Wuhan University of Science and Technology, vibration was measured on the floor and on the isolator with the ZEISS Sigma360 in the IDLE state.
As shown in Section 13, the vibration measured on the DVIA-ML1000 meets the specification (Section 9) in all three axes (Vertical, Left to Right, Front to Back).

Reference
The table below classifies vibration levels based on IEST-RP-CC012.2.
¹ As measured in one-third octave bands of frequency over the frequency 8 to 80 Hz (VC-A and VC-B) or 1 to 80 Hz (VC-C through VC-G).
² The detail size refers to the width in the case of microelectronics fabrication, the particle (cell) size in the case of medical and pharmaceutical research, etc. It is not relevant to imaging associated with probe technologies, AFMs, and nanotechnology.
The information given in this table is for guidance only. In most instances, it is recommended that the advice of someone knowledgeable about applications and vibration requirements of the equipment and processes be sought.
