摘要： The invention relates to a geodetic instrument with a telescope, an objective with a reticle in the focal plane, a clinometer and optoelectronic elements with the objective of avoiding faulty measurements due to a vibrating or oscillating target image, as well as of avoiding hanging or sticking of the pendulum and of achieving a higher measuring accuracy and of facilitating the reading of the pole. The invention is applicable particularly for compensator levels. Its task is to provide the fundamentals for an automated compensator level through the use of optoelectronic components and microprocessors and to carry out measurements on an oscillating substratum. This is accomplished owing to the fact that a luminous area or a light spot is controlled by a clinometer and located in its position by an optoelectronic receiver, and that an electric signal is generated, which triggers the display of a division mark, a pointer or its image in the image field of telescope objective, the straight line connecting the principal point of the objective and the display representing the position of the visual axis of the telescope.
