ABSTRACT:
An electronic balance with a weighing scale which is connected via a parallel guide to a system carrier, and with a translation lever which is rotatably mounted on the system carrier and onto the shorter lever arm of which the force of the weight acting on the balance scale is transferred via a coupling element and on the longer arm of which the coil of an electromagnetic compensation of force is fastened, that at least one spring touches the translation lever for the purpose of astatization, the line of application of which spring passes through the point of rotation of the translation lever. This results in a compact design and a good efficiency of astatization. It is advantageous to use a wire or a band and/or a laterally jutting-out projection on the translation lever as spring.
