Abstract
An apparatus and method for calibrating and/or adjusting a force transducer or accelerator sensor of a measuring apparatus. The apparatus including a force spring element fixedly connectable to the measuring apparatus, a mass body movable along a guide relative to the force application element and a reference force transducer or reference acceleration sensor arranged between the force application element and the mass body. A positive or negative acceleration is applied to the mass body and the reaction forces resulting from the acceleration of the mass body are applied to the force-application element and, additionally, to the force transducer or acceleration sensor in the measuring apparatus. Values determined by the reference force transducer or reference acceleration sensor and the values determined by the force transducer or acceleration sensor in the measuring apparatus are recorded, processed and compared.
