Abstract
A method estimates the effect on the weighing result of a balance () that is caused by electrostatic charges on an object () received on a load receiver () thereof. A first predefined positive voltage (U) and a second predefined negative voltage (U) of equal magnitude are alternatingly applied to a first electrode () in the vicinity of the weighing object. The forces acting on a force-measuring cell () are measured and are registered as the first and second measurement results. The difference between the respective measurement results represents the magnitude of the influence that the electrostatic charges residing on the weighing object are having on the weighing result. The difference also represents an essentially proportional part of the force resulting from electrostatic charges on the weighing object which causes a change in the weighing result and is sent as a signal to a processor unit.
