Overview
Tuning and vibration measurements were conducted on the DVIA-T87 installed at the Robocube Tech assembly hall.
Measurements were conducted with equipment installed and in a Turned on/IDLE state.
Two items requested by the customer were checked: First, whether auto-leveling behaves normally such that posture is sustained when lifting the load; Second, whether the isolator attenuates vibrations effectively even when sizable vibration occurs. These checks were validated with vibration measurement hardware.
Intrinsic floor vibrations were relatively small; additional vibration input was supplied at the customer's request while measurements proceeded.
Measurement data are presented as VC curves, with Reference guidance for interpreting vibration levels.

Conclusion
With the customer's equipment seated on the measurement location, isolator Auto-Leveling was confirmed to behave properly.
Across all axes, vibrations on the isolator top plate were observed to attenuate relative to the floor vibrations.
At measurement location 1, floor vibration Vertical at 63 Hz met VC-B, Left to Right at 25 Hz met VC-B, and Front to Back at 10 Hz met VC-A. On the isolator top plate, Vertical at 10 Hz exhibited VC-E, Left to Right at 16 Hz VC-E, and Front to Back at 10 Hz VC-B.
Auto-leveling qualification and vibration isolation measurements were jointly reviewed with the customer to close the inquiries.
