Grounding resistance measurement

  1. Make sure E, P and C leads are correctly connected.
  2. Set the rage switcher to the required resistance scale, press “TEST” button to switch on AKTAKOM ATK-5307 Digital ground tester and see the grounding resistance measurement results on the display.
  3. If you see “HΩ” symbol on the display that means the leads has got disconnected or the grounding resistance of the additional electrode is too high. Therefore check C1 and E1 connection or reduce the grounding resistance to the right level accordingly to make the grounding resistance measurement results correct. It can be done changing the auxiliary grounding electrode position or by moistening the ground with water.

Ground potential measurement

  1. Make sure E and P leads are correctly connected.
  2. Set the rage switcher to “EARTH V”, press “TEST” button to switch on AKTAKOM ATK-5307 Digital ground tester and see the grounding resistance measurement results on the display.
