Abstract
A weighing system is described in which a weighing platform is operatively coupled to a transducer arrangement included in an electrical bridge circuit having connected therein a tare resistor arrangement for balancing out the tare weight of the platform. Means are provided for selectively isolating the effect of the tare resistor arrangement from the bridge circuit so that the system output indicates the sum of the tare weight of the platform and the weight of any load on the platform, thereby enabling the weighing system to be checked using the weight of the platform.
