TH CONTINUITY CHECK - Appliance
must be electrically disconnected - meter set on W
(Ohms) x 1 scale and adjust zero if necessary.
a) Test leads from any appliance earth point to earth
pin on plug. Resistance should be less than 0.1 W
(Ohm), check all earth wires for continuity and all
contacts are clean and tight.

TION CHECK - Appliance electrically
disconnected, all switches ON.
a) meter set on W (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 W (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.
