Abstract

A measuring device for determining the relative offset between two components in a z-direction includes two measuring members. A first measuring member is affixable on a first component, and the second measuring member is affixable on a second component. Furthermore, the measuring device includes a sensor device for determining the relative position of the two measuring members. The first measuring member and the second measuring member are affixable on the first components at a rigid angle. At least one of the measuring members is able to be brought into adhesive contact with the first component or the second component. The measuring device includes support members for at least one measuring member so that the measuring member is able to assume a parking or an operating position. The measuring members are precisely and reproducibly aligned in space relative to each other in the parking position.
