Conclusion
The DVIA-ML1000 (S/N 260730R5) installed under the TESCAN MIRA LMS FE-SEM at Wuhan University of Science and Technology (Wuhan) meets the vibration specification (Section 9) on all three axes after the first tuning trial. Measurements were taken with the SEM in the Idle state.
A 7 Hz vibration peak of unidentified origin was observed on the DVIA-ML1000 top plate. Fine tuning suppressed its amplification, and the response at this frequency remains within the specification.

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 range 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 line 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.
