Summary of Work

We installed the system by

- Positioning the daeil under the microscope

We tested the system by

- Creating and uploading a site-specific tune

- Collecting vibration data to verify the performance

We left the system

- In position and turned on

Procedures

Vibration

VEC conducted vibration measurements in six directions. Acceleration measurements were taken at a bandwidth of 200Hz with units of um (Pk-Pk). The acceleration spectra with 200Hz bandwidths were recorded.
