DVIA-ULF1000 (S/N 251112R4) installation and vibration measurement at Tier-1 Semiconductor Fabrication Facility DSR C Tower 3F research lab with ZEISS GeminiSEM 460 FE-SEM.

DVIA-U1000 re-tuning worksheet (serial 220919R6-1) for Goertek Inc. with ZEISS FE-SEM Sigma 300; tuning December 19, 2025, report written January 7, 2026 (Chaewon Lee). Overview cites Z-axis oscillation and gain reduction; location line "-" (N/A). Publishes Vertical, Left to Right, and Front to Back transmissibility UI plots only; equipment picture line Photo Not Allowed; decorative header bitmap and Reference EMF omitted — Reference uses the standard VC markdown table.

DVIA-UB700 (S/N 221024R5) inspection report for ZEISS FE-SEM Sigma 300 at Hanyang University, Natural Sciences Building, Room 112. Turned on/IDLE measurements: vertical, left-to-right, and front-to-back VC curves, autospectra, and transmissibility. LPF tuning on left-to-right and front-to-back removed initial active-mode oscillation; all directions meet vibration specification at pass levels shown in the measurement summary.
