Resistance of soil between electrodes
Four-pole method (Winner method)
：
Connect the test leads as shown below.
Note the spacing between the auxiliary grounding bars and the depth of
burial,bury
H, S, ES,
and
E
auxiliary ground rods in the ground in a straight
line, connect the grounding test leads (red, yellow, green, and black) from
the
H, S, ES,
and
E
connectors of the instrument to the
H, S, ES,
and
E
auxiliary
grounding rods under test.
Auxiliary ground rod spacing setting:After connecting the test line, press
the function button
ρ
to enter the soil resistivity test mode, press and
hold the
“
SET
”
key (more than 3 seconds) to enter the spacing setting of
the auxiliary grounding rod, short press " " to move the cursor, press
" " or " " key to change the current value (value
a
range: 1m ~ 100m),
long press "
SET
" key (more than 3 seconds) to save the set value
a
and return
to soil resistivity test mode.
After setting value
a
, in soil resistivity test mode, press
“
TEST
”
key
to start the test, and count down to display the test progress. After the
test is completed, a stable soil resistivity value is displayed.
As shown in the following figure, the measured soil resistivity is
47.23
Ω
m
, the grounding resistance value
RH
of the auxiliary current electrode
is 0.34K
Ω
, and the grounding resistance value
RS
of the auxiliary voltage
electrode is 0.28K
Ω
. After this display is completed, it will automatically
return back to desplay the tested soil resistivity
ρ
.
