Abstract

A compact balance with a system carrier including a vertical plate, with a balance scale carrier including a vertical plate, whereby the plane of the system carrier and the plane of the balance scale carrier are parallel to one another, with at least three guide rods which run vertically to the plane of the system carrier and connect the balance scale carrier in the form of a parallel guide to the system carrier and with a balance scale fastened in a hinged fashion to the balance scale carrier that a lever is mounted on the system carrier which lever extends parallel to the plane of the system carrier in the space surrounded by the system carrier and the balance scale carrier and that a coupling element connects the one lever arm of the lever to the balance scale carrier whereas a coil for the electromagnetic compensation of force is fastened to the other lever arm of the lever.
