N2 - DC resistivity data by using computer-controlled multi-channel multi-electrode arrays is be popular. While, acquisition speed are enormous, optimization of the measurement technique is necessary, in order to gather without loss of data quality. The analysis of field data from multi-channel resistivity-meter "Skala 64" shows that electrode charge-up effect is cause significant distortions of measuring potentials. This effect can be larger than the induced signal and have a significant amplitude during all time of measurements. Influence of electrode grounding resistance is much lower. An algorithm for linear correction had been realized and tested. If there is a short delay before measuring potentials is provided after an electrode is used for transmitting current, correction of the linear drift allows to exclude influence of charge-up effects.
