Interfaces Instrumental e de Programação para Aquisição Automática de Dados Geoelétricos Usando Múltiplos Eletrodos

In this paper we describe a hardware and software<br>developed to perform the automatic acquisition of<br>geoelectrical data using multiple electrodes. The<br>hardware consists of an electronic switching unit<br>controlled by a personal computer trough a RS-232 line,<br>which contains a digital microcontroller that performs the<br>switching from the resistivity-IP measuring equipment<br>inputs and outputs to one of 64 electrodes of an electrode<br>set. Software part consists of a PC-based application<br>designed to control the electrode switching and to record<br>incoming data from equipment.
