Abstract
A measuring electronics serves for ascertaining a potential difference (Δφ12) between a first measuring electrode and a second measuring electrode. For such purpose, the measuring electronics comprises a reference electrode, an input circuit having two circuit inputs electrically connectable with the first, respectively second, measuring electrodes and two signal voltage outputs, a compensation circuit, a measuring and control circuit having two signal voltage inputs, two signal voltage inputs electrically and a compensation control output. The compensation circuit is adapted to provide on the first compensation voltage output a compensation voltage, namely an adjustable direct voltage referenced to the reference potential, and on the second compensation voltage output a compensation voltage, namely a direct voltage referenced to the reference potential. Additionally, the compensation circuit includes at least two operating modes selectable by means of a compensation control signal appliable on the control signal input, wherein in a first operating mode the compensation voltage is set at a predetermined voltage value, and in a second operating mode the compensation voltage is set a…
