6．Simple Method for Measuring Ground Resistance
When using the commercial power system grounding as an auxiliary
grounding pole to measure, it must be confirmed by the checker
that it is the grounding pole of a commercial power system.
Cannot use this meter to confirm grounding pole of commercial
power system
This method is a simple measurement method that does not use an auxiliary
grounding rod. The grounding electrode with the smallest grounding resistance
is used as the auxiliary grounding electrode, and two simple test wires are
connected (that is, the H and S interfaces are short-circuited).Instead of
the auxiliary grounding rods H, S, metal burying materials such as metal pipes
or fire hydrants, common grounding of commercial power systems, or lightning
protection grounds of buildings may be used.Take care to remove the oxide
layer at the connection point of the selected metal auxiliary grounding body
during measurement.
Grounding resistance simple test wiring as shown below, other operations and
