Summary of Work
We installed the system by
Providing lifting services
Positioning the daeil under the microscope
Leveling the daeil to within .5mm
Connecting the compressed air line to the air supply line for the tool
We tested the system by
Creating and uploading a site specific tune
Collecting vibration data to verify the performance
We left the system
System in position and operational
Installer's Notes
We used BYU's Microscope lift to install the Helios 1 onto the DVIA ML1000. The data shows that there was onboard vibration from the Helios at the time of data collection. The peaks are most notable at 32 and 50 Hz in the vertical direction and 25Hz in the horizontal direction. These vibrations don't exceed the specification and should not affect tool performance.
Procedures
Vibration measurements were conducted in three directions using calibrated seismic accelerometers at a bandwidth of 200 with units of m/s (RMS).
Measurement setup
Bandwidth: 200
Lines: 3200
Window: Hanning
Coupling: ICP 2mA
Average Type: Stable
Duration: 60 seconds
Engineering Units: m/s (RMS)
X Axis Scaling: 1/3 Octave
