Based on the GDP32 multi-function electric apparatus produced by Zonge Company and its application software, this paper discussed some problems concerning the practical application of CSAMT and proposed the criteria for judging the data. With practical examples, this paper discussed some correction methods of static effects, summarized the merits, demerits and applicability of one-dimensional inversion and 2D inversion. It is held that the color gradation of the resultant map can be adjusted according to different work aims and that suitable numerical processing can be made for resistivity. In the end, the author investigated the interpretation depth of CSAMT and dealt with the feasibility of confirming boundary by use of drilling data.
