The DIGI-SCHMIDT 2000 concrete test hammer comprises the actual concrete test hammer and the display unit. Both components belong together and are calibrated as one unit. The impact bolt of the concrete test hammer strikes the surface of the concrete with a defined force. After the impact, a metal body, the so-called hammer (see pos. 14 in Fig. 6.2, page 16), rebounds. The rebound distance is measured by a sensor and passed on to the display unit as an electrical signal. The sign
