In order to more effectively exploration of metal minerals as well as in geologic mapping, the authors have studied and inproved from the SuperSting R8/IP to continuous receiver by induced polarization time domain instrument of Data Logger devices. There are series of basically control systems such as: designing configuration of receiver; commutating the signal and operating control; designing electrical entrance; designing software and simultaneous measurement; technical processes and data analysis. There proved to be more effective for measurements the (VN-IP01) continuous receiver than the SuperSting R8/IP followings: the (VN-IP01) continuous receiver operated stable measurement procedures; noise reduction and isolated from the useful signal; the resistivity parameters are completely the same for two equipments; the induced polarization is different of these instruments, particularly the ore deposit; the correlation coefficient of induced polarization is related to the parameters of these equipments; the energy spectrum of the induced polarization is always higher the VN-IP01 receiver than the its SuperSting IP/R8. Therefore, the studied and inproved from the SuperSting R8/IP to the continuous receiver are capable efficiency to solve geological and mineral exploration by induced polarization time domain instrument. The results of measured data analysis of the VN-IP01 receiver are higher resolution, polarization anomalies and more accurately geological layouts.
