    摘要: A method for manufacturing-side calibration of a measuring device for capacitive fill level measurement of a medium, wherein at least one probe unit of the measuring device is activated with an electrical, alternating voltage of a predeterminable frequency. As a function of the frequency of the activating signal, a conductivity range is determined, within which the fill level measurement is essentially independent of a change of the electrical conductivity of the medium; for such conductivity range, at least a first reference matching between a predeterminable, first fill-level value and a first capacitance value belonging to the first fill-level value is produced; and the first reference matching between the first fill-level value and the first capacitance value is recorded. Additionally, the invention relates to a corresponding measuring device.
