    3. OPERATING MODE 3.1 MEASUREMENT OF THE RESISTANCE OF AN EARTH POINT To measure the resistance of an earth conductor, the so-called "62% method" is in general recommended. This measurement requires the use of the items in the Earth Kit (see Ch.6: TO ORDER).

  • Page 6: Measurement Of Resistance

    Checking the measurement 7. Note the displayed value. 8. Wait for a few moments and then re-measure. 9. Move rod S by 10% towards H, along the line between the earth point E and the rod H. Measure and note the result. 10.

  • Page 7: Fault Signals

    NB: In the case of low value resistances, it becomes necessary to take into account the resistance of the leads (approx. 22.5 mΩ/m for those supplied as accessories). To overcome the resistance of the leads, we advise the use of a (4 pole) Earth/Resistivity Tester, on 4-wire connection.
