1.1 This method covers the equipment and procedures for the field measurement of soil resistivity, both in situ and for samples removed from the ground, for use in the control of electrodes is measured using a sensitive voltmeter. Alterna-tively, the resistance can be measured directly. The resistivity, r, is then: r,V·cm 5 2p aR ~a in cm!

(astm g57) Below is a a brief background on the Wenner Four-Electrode measurement. Note: We have also written an article on how to perform the Wenner method using the SuperSting™ and an article on how to perform the Wenner method using the MiniSting™.
