| Abstract: | Digital geoelectrical equipment controlled by microprocessor may be casually deadlocked or reset when measuring the apparent resistivity due to some interferences.Through careful analysis,it is found that the fundamental interferences are from power circuit and strong electromagne tic filed, which reduce reliability of the equipment.Fortunately,the anti interference capacity and reliability of the equipment could be evidently heightened by adopting software and hardware improvement . |
