ABSTRACT:
A testing and calibrating instrument for acceleration sensors in which a pendular hammer and a pendular anvil are pivotally mounted on a support. An acceleration sensor which is to be tested and calibrated, as well as a standard acceleration sensor of known characteristics, are attached to the anvil at the level of the impact point at which the hammer strikes the anvil, the hammer and anvil being so dimensioned and positioned with respect to each other that the impact point lies at least approximately at the level of a nodal point of bending oscillations which arise in the anvil when the same is struck by the hammer.
