Multiple Earth connections:
In general, multiple earth connections to an EUT (e.g. water pipe
connections to a water heater) can cause difficulties in measurement.
This has previously needed the additional earth connections to be
isolated.
The Supernova Elite tester is capable of testing earth connections in
the presence of additional earth paths. This is done automatically by
performing a point to point measurement of the earth connection, and
measurement of the differential leakage current, rather than the earth
lead current. Measurements are thus assured without special
precautions.
