 und Diopterlineal horizontal nivelliert (in vollen Linien gezeichnete Stellung Fig. I)   mittels   der   Wagen 17 und 18   und wird der Nullpunkt des Gradbogens in der   gewöhnlichen   Weise mittels der   Kompassnndel   orientiert.   Das Resultat der Messung ergibt sich durch Ablesen auf dem Grad   bogen, sobald das Diopterlineal aus der Nullstellung gedreht und das Objekt visiert ist. 



   Beim Messen vertikaler Winkel wird das Instrument um das Universalgelenk gedreht, um die Achsen des Gradbogens und Diopterlineales horizoutal einzustellen, was die Wage 19 anzeigt. Hierauf wird das Instrument um die Achse 29 in die   gewünschte Vertikalebenc gedreht.

 and diopter ruler is leveled horizontally (position shown in full lines Fig. I) by means of the carriages 17 and 18 and the zero point of the degree arc is oriented in the usual manner by means of the compass needle. The result of the measurement is obtained by reading off the degree curve as soon as the diopter ruler is turned from the zero position and the object is sighted.



   When measuring vertical angles, the instrument is rotated around the universal joint in order to adjust the axes of the degree arc and diopter ruler horizontally, as indicated by the balance 19. The instrument is then rotated about the axis 29 into the desired vertical plane.
