Abstract
An apparatus and a method allows a determination of the degree of hardness of semisolid materials with a higher accuracy and a simultaneously lower sensitivity with respect to electronic and mechanical disruptions. An adjusted force value (F) is determined prior or during a downward movement of a force/path sensor () and the force difference (ΔF−ΔF) is determined between the adjusted force value (F) and respective measured force value (ΔF−ΔF) and a zero time (t) is determined, wherein the position (, s) of the measuring body () at the zero time (t) is used as the exact starting position (, s) of the surface of the material to be measured ().
