Answer Posted / ramesh baraskar
In this meter there will be four terminals(E, P1, P2, P3)
in which E and P1 will be shorted and connected to the grid
or electrode and P2 and P3 are reference electrodes which
will be kept on the earth surface on 90° degree
locations for taking the reference resistances of the earth.
The meter shows the resistance of the earth. But it is
neccessary that it should be below 1ohm and grid earth system below 5 ohm.
