Abstract: front page image
(EN)The invention involves the steps of: connecting a first terminal (A) of the capacitor to the midpoint (N1) of a first voltage-dividing bridge (L1); applying a first voltage (V1) to a second terminal (B) of the capacitor; keeping a voltage (V1), from a midpoint (N1) of the first dividing bridge, near a reference voltage (Vref); releasing a midpoint (N2) of a second dividing bridge (L2) by means of a constant current (I); applying a second voltage (GND) to the second terminal (B) of the capacitor when a voltage (V2) from the midpoint (N2) of the second bridge reaches a first threshold (Vref); and measuring the time needed for the voltage (V2) to reach a second threshold (Vref').
(FR)L'invention comprend des étapes consistant à : relier une première borne (A) de la capacité au point milieu (N1) d'un premier pont diviseur de tension (L1), appliquer une première tension (V1) à une seconde borne (B) de la capacité, maintenir une tension (V1) d'un point milieu (N1) du premier pont diviseur au voisinage d'une tension de référence (Vref), et décharger un point milieu(N2) d'un second pont diviseur (L2) avec un courant constant (I). Lorsqu'une tension (V2) du point milieu (N2) du second pont atteint un premier seuil (Vref), appliquer une seconde tension (GND) à la seconde borne (B) de la capacité, et mesurer le temps nécessaire à ce que la tension (V2) atteigne un second seuil (Vref').
