The electrodes misplacements are dx{},1,2 and dy{},1,2 whereas d is the uniform electrode spacing. The subscript refers to the electrode(s) with positioning error(s). The influence of electrode positioning is studied in longitudinal x and transverse y directions separately. Electrodes nomenclature: HC, high current; HP, high potential; LP, low potential; LC, low current.
