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.

If the amperometric circuit is
interrupted, when pressing
START/STOP the instrument doesn’t
manage to read the minimum current,
therefore a screen similar to the one
beside appears. Make sure that the
terminals are connected correctly and
that the amperometric rod (blue
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.
