Press START push-button to start the measurement.
Repeat the measurements (points 3, 7, 8) shifting the volt-
age electrode several metres: the electrode should be
S
shifted farther and closer to the earth electrode being
tested. If R
by more than 3%, the distance of the current electrode
from the earth electrode being tested should be consider-
ably increased and the measurements should be re-
peated.
