    摘要: Die Erfindung betrifft ein Widerstandsnetzwerk (50) für eine Kraftmessvorrichtung (1), insbesondere eine Waage, mit mindestens zwei elektrischen Teilwiderständen (R1, R2, R3, R4), welche abgestufte Widerstandwerte aufweisen, sodass jeweils eine unterschiedliche elektrische Verdrahtung der Teilwiderstände (R1, R2, R3, R4) einen unterschiedlichen Gesamt-Widerstandswert (R) des Widerstandsnetzwerks (50) ergibt. Dabei weist das Widerstandsnetzwerk (50) zur Verdrahtung der Teilwiderstände (R1, R2, R3, R4) ein codierendes Schaltelement (SW) auf, sodass verschiedenen Schaltstellungen (POS) des Schaltelements (SW) verschiedene Verdrahtungen der Teilwiderstände (R1, R2, R3, R4) zuordenbar sind und die Anzahl der Teilwiderstände (R1, R2, R3, R4) geringer ist als die Anzahl der möglichen Schaltstellungen (POS).
