R
——
meter readings, total grounding resistance of the entire grounding
system;
r1

rn
——
are all independent grounding points, and grounding bodies are
not connected together under the ground;
RH
——
ground resistance of auxiliary current pole
H
;
RS
——
ground resistance of auxiliary voltage pole
S
;
n
——
the number of independent grounding points, the more points, the
smaller the
R
value.
After connecting the test line, press the function button
R
to enter the
ground resistance test mode, and press the
“
TEST
”
key to start the test.There
is a countdown indication during the test and stable data is displayed after
the test is completed. That is, the grounding resistance value
RH
of the
grounding resistance value and the auxiliary current pole
H
, the grounding
resistance value
RS
of grounding resistance value
R
and auxiliary voltage
pole
S
.
As shown in the following figure, the tested grounding resistance is 2.77
Ω
, the grounding resistance of the auxiliary current RH is 0.27K
Ω
, and the
grounding resistance of the auxiliary voltage electrode RS is 0.22K
Ω
.
