4.6.4. Anomalous cases which may occur during EARTH ρ tests



If the voltmetric circuit (red and green

cables) is interrupted, when pressing

START/STOP the instrument doesn’t

manage to read the minimum voltage,

therefore a screen similar to the one

beside appears. Make sure that the

terminals are connected correctly and

that the voltmetric rod (red conductor)

has not been driven into a gravely or

scarcely conductive ground. If

necessary, pour water around the rod.



In case both the amperometric circuit

and the voltmetric circuit are

interrupted, when pressing

START/STOP the instrument doesn’t

manage to read the minimum current

nor the minimum voltage, therefore a

screen similar to the one beside

appears. Make sure that the terminals

are connected correctly and that the

amperometric and voltmetric rods (blue

and red conductors) has not been

driven into a gravely or scarcely

conductive ground. If necessary, pour

water around the rod.

rP indicates an

high resistance

value.

rC indicates an

high resistance

value.

rC and rP indicate

a high resistance

value both for the

voltmetric circuit

and for the

amperometric

circuit.
