As the measured "apparent" conductivity is influenced by the height of the instrument above the surface and its position, it is advantageous to transform it into real apparent resistivity which is independent of the mentioned factors. By determining the difference of apparent resistivities calculated from measurements made at different heights and positions, the effect of different depth ranges can be evaluated (see in this volume : Jászdózsa).
