Abstract
The hardness measuring device () is provided with a) a penetration body (), which penetrates a workpiece () along a penetration vector () during a measuring process, b) a housing () which embodies a guide track () for the penetration body () which moves along said guide track () between a rest position and a measuring position and with a mechanical drive (spring), which engages with the penetration body (), at least in the rest position and which fixes the test force or the test impulse for a measuring process and c) an electronic control circuit (), which controls the measuring process and which determines a hardness value from the movement and/or the penetration action of the penetration body () into the workpiece (). The hardness measuring device () comprises an acceleration sensor (), which produces an angular signal, depending on the angle which the penetration vector () makes with the local gravitational vector (). The angular signal is supplied to the control circuit (), which, on taking into account the known mass of the penetration body () and parts connected thereto, calculates a correction value for a precise hardness measurement.
