Note
● Check the ground humid where the auxiliary stakes will
be placed. If the groud is to dry, moist it a little. Rocky
and sandy soils alson need to be moisted before testing.
● If the test site is in an urban center covered in concrete
and difficult access to the stakes, use two steel plates
25cmx25cm(or the stakes pre-existing), place them ho-
rizontally over the concrete surface then cover it with a
moist cloth. Replace the measure earth in this situation,
because in general cases it still can be used.
B. Earth Voltage Measure
WARNING
The earth voltage test only works in V and E. The C and P
cables must be separated, otherwise, the device is in risk
of being damaged and the user suffer injuries.
Select the function EARTH VOLTAGE for voltage exhibition
on the display. Conect tghe probes in V and E then conect
to the test point. The earth voltage value will be exhibited on
the display. In this case of measure, the button TEST do not
need to be pressed.
If the measure value is bigger than 10V, turn off all the volt-
age related equipaments then wait until the display reads
zero, otherwise, the residual voltage will affect the earth
resistance precision.
