Overview
After installing the DVIA-MB1000 platform, vibration on site was surveyed to verify that the SEM can be used without issues.
With the DVIA-MB1000 actively isolating, vibration on the SEM deck was measured before and after SEM operation.

Measurement conditions and results
Measurement condition
The building floor slab and the top surface of the isolation platform were surveyed.
Measurement summary
| Test condition | Measuring location | Z | X | Y |
|---|---|---|---|---|
| SEM off | Floor | C | E | E |
| DVIA-MB1000 platform top | F | F | G | |
| SEM on | Floor | D | E | E |
| DVIA-MB1000 platform top | F | F | G |
The laboratory was located on the 5th floor; factories occupy lower floors with machinery running continuously, and neighboring labs run pumps continuously (a demanding environment).
The floor under the DVIA-MB1000 measured Z axis Class D, X axis Class E, and Y axis Class E.
The top of the isolation platform measured Z axis Class F, X axis Class F, and Y axis Class G.
VC-class curves are attached.
Imaging showed some noise ingress; images will be retaken in the evening when machinery is off and traffic is low, then feedback will be provided.
