Transports electrical equipment and instruments to designated locations, and directs and assists in
laying out and connecting cables, electrodes, instrument panels, and other electrical equipment.
Adjusts electrical instruments to eliminate electrical interferences from earth currents or weather
conditions. Opens and closes circuits to send electrical current through electrodes into earth.
