During Testing of Maintenance Free Earthing, How deep should
be the Spikes of Earth Test Meter should be inserted in the
soil(one spike is 15 Meter & Other spike is 30 Mtrs away
from the Main Earth Electrode. Because, recently, we
observed that when spike is inserted 3-4 Inch in the earth-
results are better, If spike is inserted 1 feet deep than
results are increasing.
