Voltmetre differentiel d'occasion mesure

Voltmètre differentiel Bordeaux

Le voltmètre différentiel est la forme améliorée des instruments mesure DC/AC tel que le multimetre. Ici la source de tension DC/AC inconnue s’applique au rectificateur qui convertit la tension AC en DC avec une magnitude équivalente. Le courant continu résultant de cetype de montage pour éliminer le bruit s’applique au potentiomètre pour le comparer à la source de tension standard.
