(4) Earth Resistance Measurement
Select a Range (any Range is ok) when the connection is done, and
press the TEST Button. A message “
“ is displayed
at the upper right on the LCD. The measured earth resistances “Re” are
displayed on the LCD when a measurement is finished. (Fig.35)
Pressing the Cursor Key “
” displays the Result Display Screen
(Fig.36) to view each parameter.
Press the “
” Key to return to the Main Screen.
Note) The readings may not correct when the auxiliary earth resistance is
too high. Stick the Auxiliary Earth Spikes S(P) and H(C) in the moist
part of the soil. If a message “
” or “
”
appear on the LCD, auxiliary earth resistance is too high to make
measure-ments. Recheck the connection of Test Leads.
Give enough water where the spikes have to be stuck into the dry,
stony or sandy part of the earth so that it may become moist. In
case of concrete, lay the Auxiliary Earth Spike down and water it, or
put a wet cloth etc. on the spike when making measurements.
