Abstract
The device for measuring distances consists of a column (1), a slide (14) with an adjusting member (5) and a measuring element (6) which are connected with each other by way of a spring (16), a control device (19) for obtaining a constant measuring force, and by way of a precision adjusting means (39) which can be activated and deactivated. The latter exhibits a slidingly supported plunger (40) through which extends a rod (41) connected to the measuring element (6); this rod can be locked or unlocked in the plunger (40) by a screw (48) serving as a resetting means. An eccentric (40) engages into a cutout (50) of the plunger (40) and permits precision adjustment of the measuring element (6) for tracing purposes upon locking of the rod (41). With the precision adjusting means (39) being deactivated, the device is usuable for customary vertical measuring with measuring pressure control.
