A. EARTH CONTINUITY CHECK

Appliance must be electrically disconnected - meter set on

Ω

(Ohms) x

1 scale and adjust zero if necessary.

— Test leads from any appliance earth point to earth pin on plug.

Resistance should be less than 0.1

Ω

(Ohm), check all earth wires

for continuity and all contacts are clean and tight.

B. INSULATION CHECK

Appliance electrically disconnected, all switches ON.

a) meter set on

Ω

(Ohms) x 1 scale.

Test leads from L to N in appliance terminal block. If meter reads
«0» then there is a short circuit.

b) meter set on

Ω

(Ohm) x 100 scale.

Repeat test with leads from L to E. If meter reads less than

∞

(infinity) there is a fault.

NOTE - Should it be found that the fuse has failed but no fault is indicated -
a detailed continuity check (i.e. by disconnecting and checking each
component) is required to trace the faulty component.

It is possible that a fault could occur as a result of local burning/arcing but
no fault could be found under test. However a detailed visual inspection
should reveal evidence of burning around the fault.
