The measuring device was SAS4000 terrameter manufactured by ABEMSweden with a power supply 12V external battery. It measures both the transmitted current and voltage and stores these quantities together with the resistivity data. ... During our data acquisition, we select the Wenneralpha array technique for all the nine lines because it has a ...
