Abstract
Various embodiments include methods for determining an electrical fault of a conductivity sensor for ascertaining the electrical conductivity of a medium using a conductivity principle, wherein the conductivity sensor comprises a first electrode pair fully disposed in the medium comprising: applying an electrical alternating voltage to the first electrode pair; measuring a temporal profile of the electrical alternating current at the first electrode pair resulting from application of the electrical alternating voltage at the first electrode pair; ascertaining a current-amplitude characteristic value from the temporal profile of the electrical alternating current; and identifying an electrical fault of the conductivity sensor if the current-amplitude characteristic value is below a first current threshold value or above a second current threshold value.
