Abstract
Before each actual resistance measurement, a first preliminary measurement with short-circuited measuring circuit and a second preliminary measurement with the measuring circuit operating at no-load are carried out. From the measured values of the preliminary measurement steps, a weighting factor is calculated, by which, subsequently, the difference between the actual measured value and the short-circuit value is multiplied to form the actual measurement results.
