Isolation from disturbances, particularly from foundations of high precision instruments, is achieved through either passive or active vibration control systems.
Experimental results show that the circuit provides accuracy and stability in the range from 1 MΩ to 100 GΩ comparable to high precision instruments requiring high voltage and long measurement time: accuracy lower than 1%.
Motivation: Systematic bias in mass measurement adversely affects data quality and negates the advantages of high precision instruments.
Any high-precision instrument that we are offered will be lubricated with vast quantities of snake oil.
This study focuses on the foundation design and vibration isolation of a high-precision instrument subjected to ground-borne vibrations.
His expertise in high-precision instrument photography is world-renowned.
However, the above approach was prone to be the errors from assembled two or more sensing elements and the complexity of the coupling calculations, and its accuracy also depends on the high-precision instrument system.
To build in quality, we will go beyond visual inspections and use high-precision instruments to measure several parameters.
Measurements with borehole strainmeters and other high-precision instruments for inland earthquakes have also shown no indication of clear precursory deformation (Johnston et al., 1987, 2006).
Since then, various countries from around the globe contributed major funding to tsunami research and mitigation, enabling the installation of hundreds of new high-precision instruments, the development of new technology and the establishment of more modern communication systems.
