Abstract: A goniometer has a base defining a standing axis, a structure rotatable around the standing axis relative to the base, an angle encoder, and a control and processing unit. The structure has a graphic electronic information display arrangement having at least two display zones for displaying user guidance information and/or measuring information, a first of the at least two display zones being arranged in a first radial alignment relative to the standing axis on the structure. A second of the at least two display zones of the information display means is arranged in a second radial alignment relative to the standing axis on the structure, the first radial alignment and the second radial alignment enclosing an angle of at least 90°. The at least two display zones are automatically individually activated by the control and processing unit as a function of a fulfillment of a stored angular position criterion.
