Abstract:

In this paper the technical indexes,principle,function of a new specialized electrotelluric measuring instrument(Model-ZD9)developed by authors is introduced. This instrument can be used for routine observation of earth electric field at field stations and to detect deep earth resistivity by using the tensor method. It can also be used in other cases where multi-channel data collecting is required. The tests of various performances and long use in earthquake sites show that the instrument can meet the needs of observing the geoelectric field.
