How To Check Earth Resistance Using Multimeter. Ensure that the RED probe is connected to VΩma terminal while the BLACK probe is connected to COM terminal. Turn the dial to V measuring mode.
If you find out that the rods resistance is below 25 ohms. To prepare a multimeter. A ground on what.
First insert the black test lead into the COM jack.
Measure resistance on lowest Ohms scale on meyer between the ground prong on the outlet and the end of the test wire. What is earthing in electrical t. If the number on the screen is less than 1 067 025 etc the setting is too high. Then put the meter on the lowest resistance scale and measure.
