Abstract:
The invention relates to a method for testing the proper functionality of an elevator, in which a car (3) is movable in an elevator shaft having an elevator shaft excavation space, and a characteristic value is ascertained under predefined test conditions to determine the proper functionality of the elevator. To simplify the method, it is proposed according to the invention that a change of the distance (A) between a car lower side and a fixed measuring point in the elevator shaft excavation space be measured to ascertain the characteristic value.
