WebBoth measurements were made in the temperature range from 2 to 400 K. Measurements of the specific heat in the temperature range from 260 to 380 K were made using the 2 τ relaxation method with the heat capacity option of the PPMS. Samples of ~10 mg were attached to the platform with Apiezone H. 3. Results and Discussion WebSince earth has comparatively low resistivity, a voltage drop occurs near the electrode from which the current used to make the measurement flows. Consequently, in order to accurately measure the resistance value of each grounding electrode (the E electrode, S [P] electrode, and H [C] electrode), you must move about 10 m away.
