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).

1. Connect terminal E to the earth to be measured.
2. Check that the bar  

4

  is not present between terminals S and H.

3. Drive in (completely if possible) the input earth rod H at a distance "a" from the earth point

(E) to be measured.
Note: this distance is further for a deep and extended earth point (larger range of influence).

4. Drive in the rod S at 62% of the distance between the earth E and the rod H (the rods S,

H and the earth point must be in line).

5. Connect the rods to their respective terminals with the leads.
6. Press the "MEASURE" button  

11

  and hold the button during measurement. Check that

none of the three indicators are flashing, otherwise, check the wiring (see Ch.3.4: FAULT
SIGNALS) and make the measurement again.
