n. DG-1332, Page 21 standardized cumulative absolute velocity See Cumulative Absolute Velocity (CAV). time history recorder An instrument capable of sensing and recording acceleration versus time. The resulting recorded time histories may be stored locally and/or transmitted to other storage devices for processing and permanent storage. The components of the time-history recorder (acceleration sensor, recorder, seismic trigger) may be assembled in a self-contained unit or may be separately located. triaxial Able to measure a variable in three mutually orthogonal components (directions), one of which is usually vertical; applies to description of the function of an instrument or group of instruments.
