Danger
To avoy eletrical shock risks, be careful when using a
grounding point of commercial electric power systems
as a point of reference test.
This method can be used when there is not possible to use
the auxiliary stakes. The two wire test method (using the
terminals E and P/C) can be applied in grounding of build-
ings, grounding wire, showers, etc., using the grounding of
the object to be measured, as Figure 3:
Figura 3
When using this method, P and C must be conected at the
same time.
