The Advanced Diagnostic test provides a specific impedance value, a polarity value, and a circuit
quality assessment of Good, Poor, or Fault. For more information about the Good, Poor, and
Fault condition labels, see Table 3. AEFD condition labels.

Condition label
Impedance Range
Description
Good
>=120kΩ
Measurements of at least 120kΩ earth-to-ground pose no risk of causing an earth
fault.
Poor
> 60kΩ < 120kΩ
Measurements between 60kΩ and 120kΩ earth-to ground do not cause an earth
trouble, but they indicate poor quality of earth fault isolation.
Investigate to prevent a future problem. Several channels that qualify as Poor can
cause an earth fault trouble at the panel that Location Search diagnostic will not
be able to isolate and find.
Fault
<=n 60kΩ
Measurements of less than 60kΩ cause an earth fault trouble. This circuit must be
investigated and wiring or devices need to be replaced.
