DVIA-T78 (serial 211213R1) installation report for WONIK IPS Jinwi site, 4F wafer analysis lab. Re-tuning and vibration measurement on December 12, 2025, with Bruker Nano Indentation tester TS77 on the isolator. Overview notes a return visit due to high vibration against Bruker self-test criteria; conclusion confirms good isolator performance in all directions while Bruker cited rubber pillars below the tool and planned equipment modification with headquarters. UI plots: VC curves, autospectra, and transmissibility by axis. Reference publishes the standard VC criteria table.
