During clamp method dual-resistance, if the measured
value display overflow, then the measured resistance exceeds the
measuring range of the instrument or description does not shut up
any metal clamp around the conductor or the grounding line under
test
(2) Four-leads method
Using the connection method as Figure 6. At this point click "
Four-leads" button, enter the interface to the Four-leads method.
And then "test" button can be measured more accurately measured
grounding resistance of grounding.

After each measurement, the measurement results can be
