HITACHI SEM SU3500 DVIA-MB1000 program P29 — Kyungsan Tyco AMP vibration survey (2016-09)

(Kyungsan Tyco AMP)

Target equipment : HITACHI SEM _ SU3500

Trip date : 2016.09.06 (Tue)

Report date : 2016.09.07 (Wed)

Field engineers : Du-hyun Kim (DAEIL SYSTEMS), Jong-wook Lim (DAEIL SYSTEMS)

After installation of the isolation platform, the vibration environment was measured to confirm suitability for SEM operation.

Survey date : 2016. 09. 06 (Tue), Engineer : Jong-wook Lim (DAEIL SYSTEMS).

Measurement location : Kyungsan Tyco AMP.

Equipment model : HITACHI SEM ( SU3500 ).

Measurement conditions : Vibrations measured on both the tabletop of the isolation platform and the slab of the laboratory building.

With the platform installed at the surveyed floor slab, VC-Class readings were measured at Z-axis A-Class, X-axis C-Class, and Y-axis C-Class.

Above the tabletop, readings were VC-Class Z-axis E-Class, X-axis F-Class, and Y-axis F-Class.

Imaging performance after isolation installation was favorable.

With the instrument’s embedded program applied, performance measurements show approximately −30 dB at the 10 Hz reference across axes.

Attached here are VC-Class curves and embedded-program transmissibility plots.
