Abstract : This patent discloses a shaker for performing both absolute and comparison accelerometer calibration. A reference accelerometer is mounted within or attached to a shaker head and calibrated with the shaker head by an absolute method. The shaker, thus calibrated absolutely, becomes a portable device for performing comparison calibrations on other accelerators which can be mounted on its shaker head. (jhd)
