A. EARTH CONTINUITY CHECK -

Appliance must be electrically

disconnected - meter set on

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

wires for continuity and all contacts clean

and tight.

B. INSULATION CHECK - Appliance

electrically disconnected, all switches ON.

a) meter set on

Test leads from L to N in appliance

terminal block. If meter reads «0» then

there is a short circuit.

b) meter set on

Repeat test with leads from L to E. If meter

reads less than

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.
