Abstract

APPAREIL PERMETTANT DES MESURES D'ATTENUATION OPTIQUE ET ELECTRIQUE DE LIAISONS INSTALLEES AINSI QUE LE CONTROLE DE CONTINUITE. IL COMPORTE DES AMENAGEMENTS ELECTRIQUES POUR PRODUIRE UN SIGNAL DE TEST S1 CORRESPONDANT AU COURANT D'EMISSION ET POUR MODULER L'EMETTEUR 1-2 A UNE FREQUENCE AUDIBLE, AINSI QUE DES AMENAGEMENTS MECANIQUES POUR L'ADAPTATION DES BORNES DE RACCORDEMENT 8-9, AUX CONNECTEURS D'EXTREMITE DE LA LIAISON, ET POUR SEPARER L'EMETTEUR DU RECEPTEUR AU MOYEN DE BOITIERS DISTINCTS 10E, 10R ET D'ALIMENTATIONS SEPAREES 7E, 7R. LES ALIMENTATIONS COMPORTENT DES BATTERIES 61E, 61R ET UN RACCORDEMENT AU SECTEUR POUR L'ALIMENTATION LOCALE AVEC RECHARGE DES BATTERIES. L'INVENTION S'APPLIQUE AVANTAGEUSEMENT A UNE EXPLOITATION SUR CHANTIER.
