LOW CONTINUITY MEASUREMENT
CONTINUITY MEASUREMENT ON PROTECTIVE CONDUCTORS
PURPOSE OF THE TEST
Check the continuity of:
NOTE: This test is to be preceded by a visual check verifying the existence of yellow-
green protective and equalising potential conductors as well as compliance of
the sections used with the standards' requirements.
