ABSTRACT:
The invention discloses an electronic balance with a scale on top, a balance scale, a balance scale carrier, two identical guide rods (7,8) which connect in an articulated manner the balance scale carrier and the balance scale in the form of a parallel guide to a system carrier (1/5) fixed to the housing and with at least one corner-load adjustment lever (22') which is connected to the system carrier via a thin area (24) and which carries a support point in the vicinity of this thin area (24) for the end of a guide rod (7) on the system carrier that the corner-load adjustment lever (22') is bent at right angles between the support point of the guide rod (7) and the thin area (24) to the system carrier (1,5) in such a manner that the moving joint (17) of the guide rod (7) and this thin area (24) are at the same height. As a result, even great forces in the guide rods such as those which occur at an off-center loading of the balance scale do not cause any torque on the corner-load adjustment lever and thus result in a very stable corner-load adjustment.
