Abstract
A method for operating a balance includes: (a) introducing an ion cloud into a weighing chamber to bring an electrostatic charge state of a weighing sample towards an electrostatic neutral state, (b) detecting the neutral state, and (c) acquiring measured values of a weighing sensor, calculating therefrom a final weighing value representing the electrostatic neutral state, and outputting the final weighing value. When the ionizer is activated, the measured values of the weighing sensor are acquired, preliminary weighing values are calculated from the measured values and the final weighing value is calculated and output after a number of preliminary weighing values have been recognized as stable. During a recognition phase, positive and negative ion clouds are alternatingly generated, and during a neutralization phase, only ion clouds of that sign are generated that, in the recognition phase, had led to the larger changes within the preliminary weighing values.
