Abstract (en)
[origin: EP1089065A2] The device has a length measurement device for coupling to a movement in the load direction, a frame (4) for connection to the penetration depth measurement device and connected to an elastically deformable part (6) for absorption of a load in the load direction (2). The frame accepts a measurement sensor (11) in contact with a base plate (2) during calibration. An adjuster (7) moves the frame in the load direction to perform calibration. Independent claims are also included for the following: a method of calibrating a penetration depth measurement device for a hardness testing machine.
