Caution Note: For energized services first check the earth electrode voltage with connections as shown in video. If its more than 10V don't proceed. (E terminal=dummy, P to Potential spike (Yellow), C to Current spike (Red) and V to earth electrode (Green) under test. Turn rotary knob to Earth Voltage position. Now voltage present will be displayed. No need to press test button. If display shows 10V or more Deenergize the earthing system carefully and then proceed.
During resistance checking pull out green probe from V terminal and inset it into E terminal. ie leave V terminal dummy.
