Electronic balance equiped of a circuit of the weight of the calibration

摘要

For an electronic balance, equipped with a weight calibration circuit 13 / 20 / 28 / 41 / 40 and a digital signal processing unit 18 for the purpose of the automatic control of the circuit of the weight of the calibration, it is proposed to incorporate a proximity sensor 45 to the balance and to lock the automatic control of the circuit of the weight of the calibration by the digital signal processing unit 18, as soon as the proximity sensor 45 delivers an output signal. / p & & p & application: in particular to the weighing
