Test Procedure A
Basic Earthed (Class I) Products
Earth Continuity Test
15. Firmly apply the Earth Probe, for 3 - 6 seconds, to all exposed, unpainted, metalwork on the product in turn
and check that the green PASS lamp on the probe lights and the Earth Circuit meter reads below 0.5 ohms,
i.e. within the un-coloured or orange bands, at each test point.
16. Take particular care, with multi-branch luminaires, to test each branch fully – paying particular attention to
exposed metal that is furthest from the Earthing terminal, to ensure that joints between base / arm / shade etc
are fully sound.
17. For products with exposed brass lampholders also make sure that these are tested – do not apply the probe
to either of the live pins.
18. Following a satisfactory test, release the probe and stow it out of the way in the holder provided.
19. If the green PASS lamp fails to come on, or remain on, whilst the test is applied, the Earth resistance exceeds
the permitted 0.5 Ohms – the meter pointer will be in or above the red zone.
This may be caused by - loose / broken earth wires - loose or corroded joints - applying the probe to
lacquered surfaces, or making poor contact - even missing Earth wires. Correct any faults before continuing.
