Abstract: In a method and device for setting one or more measuring points on a specimen in a specimen holder for automated hardness testing in a hardness-testing device, the hardness-testing device has a table, a tool holder with a penetrator and at least one lens. The specimen holder with the specimen is positioned on the table in the x- and y-directions. The table and/or tool holder can be moved in the z-direction, relative to one another. A virtual three-dimensional model of the specimen holder and specimen is selected from data storage, and the model and/or an overview image of the specimen is depicted on a screen. Then, a point is marked in the image, and one or more measuring point is/are automatically defined based on the measuring method selected. To each measuring point, the z-coordinate is automatically assigned in the hardness-testing device based on its x- and y-coordinates and virtual model.

Abstract: A hardness testing device has at least one penetrator (9), arranged on a holder (15), for producing an impression (27) in an object under test (3) and at least one lens (12) for detecting at least one measure of the impression (27) in the object under test (3), which can be positioned alternately over the object under test (3). The holder (15) is mounted on the hardness testing device (6) in such a way as to be able to rotate around its longitudinal axis.
