Balancing device for balancing a microscope with respect to a rotation axis, the balancing device comprising: - a balancing weight arranged around and fixed to the rotation axis, such that the balancing weight is rotatable around the rotation axis, wherein a center of mass of the balancing weight is arranged apart from the rotation axis; - a lever for indicating a torque acting on the balancing device and/or on the balancing weight, wherein the lever is arranged around and fixed to the rotation axis to be rotatable around the rotation axis, wherein the lever extends within the balancing weight and is movable by the torque within a predetermined range with respect to the balancing weight, and wherein an electrical potential of the lever is set to a predetermined first potential value; - at least one stopper element, which is immobile with respect to the balancing weight and forms at least one end point of the range of the lever, wherein the stopper element and the lever are in electrical contact when the lever is arranged at the at least one end point of the range and wherein the lever and the stopper element are electrically isolated from each other when the lever is apart from the at least one end point; - control means configured to set an electrical potential of the stopper element to a predetermined second potential value different from the first potential value at least when the lever is apart from the at least one end point, to observe the electrical potential of the stopper element and/or of the lever and to indicate the lever being arranged at one of the least one end points when the electrical potential of the stopper element departs from the predetermined second potential value and/or when the electrical potential of the lever departs from the predetermined first potential value. - a balancing weight arranged around and fixed to the rotation axis, such that the balancing weight is rotatable around the rotation axis, wherein a center of mass of the balancing weight is arranged apart from the rotation axis; - a lever for indicating a torque acting on the balancing device and/or on the balancing weight, wherein the lever is arranged around and fixed to the rotation axis to be rotatable around the rotation axis, wherein the lever extends within the balancing weight and is movable by the torque within a predetermined range with respect to the balancing weight, and wherein an electrical potential of the lever is set to a predetermined first potential value; - at least one stopper element, which is immobile with respect to the balancing weight and forms at least one end point of the range of the lever, wherein the stopper element and the lever are in electrical contact when the lever is arranged at the at least one end point of the range and wherein the lever and the stopper element are electrically isolated from each other when the lever is apart from the at least one end point; - control means configured to set an electrical potential of the stopper element to a predetermined second potential value different from the first potential value at least when the lever is apart from the at least one end point, to observe the electrical potential of the stopper element and/or of the lever and to indicate the lever being arranged at one of the least one end points when the electrical potential of the stopper element departs from the predetermined second potential value and/or when the electrical potential of the lever departs from the predetermined first potential value.
