Abstract of the Disclosure A method for the calibration or checking of dynamo- meters consisting in that a force is applied to the dynamometer subjected to calibration or checking through a master dynamo- meter. The force applied is progressively changed in magnitude, and after each such application the force applied to the dynamometer subjected to calibration or checking is retained, simultaneously relieving the master dynamometer of the force. In said method, a force is also applied directly to the dynamo- meter subjected to calibration or checking by means of standard weights. An apparatus for the calibration or checking of dynamometers incorporating two frames whereof one is rigidly attached and the other is movable relatively to the first one. Interposed between the frames is the dynamometer subjected to calibration or checking and interacting therewith is a means of applying a force which applies a calibrated force through the master dynamometer. The apparatus incorporates one more means of applying a force installed with provision for apply- ing the force only to the dynamometer subjected to calibration or checking which also assures that the master dynamometer is relieved of the force applied. me method and apparatus offer the prospect of checking and calibrating dynamometers against forces in excess of 10,000 kN with practically no upper limit and an error never higher than anywhere between 0.25 and 0.5%.
