.
The distance between the measured grounding body E and the
current pole H should be at least 5 times the buried ground depth
(h) of the measured grounding body, or 5 times the buried ground
electrode length (d).
Measure the total grounding resistance of a complex grounding
system. The distance d is the distance of the largest diagonal
of the grounding system.
During the test, the test leads cannot be intertwined with each
other. Otherwise, the test accuracy may be affected.
For a multi-point independent grounding system or a geodetic grounding
system, the user can choose a longer test line, and the electrode spacing
is greater than 5 times the maximum diagonal length of the tested network.
