Abstract: This invention concerns a meter for measuring polarisation induced in the earth and in particular for measuring transient voltages that follow the termination of direct current flow through the ground. In this device automatic normalisation of the data is achieved by correllating the voltage source producing the transient voltages with the potential measured across measurement electrodes in such a manner that the voltage source and measurement circuits are not otherwise electrically linked.
