Claims (1)

<Desc/Clms Page number 4> EMI4.1 des Gespräches) eine Spannung aufweist, welche einerseits die Leitung besetzt hält und andererseits in den Wicklungen des Zählers Ströme zustandekommen lässt, die in ihrer Wirkung auf den Anker einander entgegenarbeiten, während beim Zählen an der Prüfleitung ein Spannungsabfall erzeugt wird, der die Leitung noch besetzt hält, bei welchem aber die Ströme in den Zählerwicklungen in ihrer Wirkung auf den Anker einander unterstützen, zu dem Zwecke, eine kräftige Zählererregung bei einer verhältnismässig geringen Änderung der Spannung an der Priifleitung zu erhalten. <Desc / Clms Page number 4> EMI4.1 of the conversation) has a voltage which on the one hand keeps the line occupied and on the other hand allows currents to develop in the windings of the meter that counteract each other in their effect on the armature, while when counting on the test line, a voltage drop is generated that still occupies the line at which, however, the currents in the meter windings support each other in their effect on the armature, for the purpose of obtaining a powerful meter excitation with a relatively small change in the voltage on the test line. 3. Ausführungsform der Schaltung nach Anspruch 1, dadurch gekennzeichnet, dass der EMI4.2 Teilnehmerleitung (aI33, bd33) an die Prüfleitung (cl geschaltet und für die Dauer der Verbindung zusammen mit der Wicklung (2) des Priifrelais in dessen geschlossenem Stromkreis eingeschaltet gehalten wird, zu dem Zwecke, die Zählung einerseits in einem beliebigen Zeitpunkte während der Verbindung vornehmen zu können und andererseits den Zählerelektromagneten erst nach erfolgter Prüfung anzuschliessen. EMI4.3 3. Embodiment of the circuit according to claim 1, characterized in that the EMI4.2 Subscriber line (aI33, bd33) connected to the test line (cl and kept switched on for the duration of the connection together with the winding (2) of the test relay in its closed circuit, for the purpose of counting on the one hand at any point in time during the connection to be able to and on the other hand to connect the counter electromagnet only after the test.
