EMI1.1
Die Erfindung betrifft eine Messeinrichtung zur Ermittlung der Kapazitätsbeziehungen zwischen Teilen eines Doppelsprechstromkreises mit Hilfe von Wechselstrom und einer Wheatstoneschen Brücke. Mit der erfindungsgemässen Einrichtung wird bezweckt, die bisher erforderliche Schreib- und Rechenarbeit durch unmittelbare Ablesbarkeit der endgültig erforderlichen Ausgleichkapazitäten und damit eine Quelle von Irrtümern zu vermeiden und Zeit beim Messen zu ersparen. Erfindungsgemäss wird dies durch die Anwendung von vier Messkondensatoren erreicht, die einzeln oder paarweise und auch alle vier zeitweilig miteinander mechanisch gekoppelt und eingestellt werden können.
Zur Erläuterung der Messeinrichtung sei an Hand der Zeichnungen die Durchführung einer Messung beschrieben.

EMI1.1
The invention relates to a measuring device for determining the capacitance relationships between parts of a double-talk circuit with the aid of alternating current and a Wheatstone bridge. The aim of the device according to the invention is to avoid the previously required writing and arithmetic work by making the finally required compensation capacities immediately legible and thus a source of errors and to save time when measuring. According to the invention, this is achieved through the use of four measuring capacitors which can be mechanically coupled to one another and adjusted individually or in pairs and also all four temporarily.
To explain the measuring device, the implementation of a measurement is described with reference to the drawings.
