Abstract: A spirit level has a first inclination sensor, at least one second inclination sensor, and a display to represent an inclination for the at least one second inclination sensor based on an inclination for the first inclination sensor. The display may represent the inclination for the at least one second inclination sensor as an inclination relative to the inclination at the first sensor. At least one of the inclination sensors may have a changing inclination. In this case, the display represents the inclination for the at least one second inclination sensor based on the changing inclination. The inclination sensors may be movable with respect to a remainder of the spirit level. In this case, the inclination sensors may be connected to the remainder of the sprit level with a cable or high frequency radio links.
