5. Grounding resistance measurement
When turning on the
G-TEST
, the display will show the opening message,
followed by the parameters
Earth Resistance / 3-Pole / 270Hz
. These are
the standard functions and frequency; to operate in the 1470Hz frequency,
press the
1470Hz
1
key.
Insert the auxiliary rods (current rod
E3
and voltage rod
E2
) in the ground.
Using the cables supplied with the equipment, connect the rods to the
H
$
and
S
#
output terminals, respectively. The grounding system under test
must be connected to
E
!
with the 5 meter cable.

”, and after a few moments
the resistance value will appear, as in the following example:
R= 10.01@
3_Pole 270Hz
The result will then be stored on the memory.
