24A. EARTH CONTINUITY CHECKA. EARTH CONTINUITY CHECKA. EARTH CONTINUITY CHECKA. EARTH CONTINUITY CHECKA. EARTH CONTINUITY CHECKAppliance must be electrically disconnected - meter set on W (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 W (Ohm), check all earth wiresfor continuity and all contacts clean and tight.B. INSULAB. INSULAB. INSULAB. INSULAB. INSULATION CHECKTION CHECKTION CHECKTION CHECKTION CHECKAppliance 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 eachcomponent) is required to trace the faulty component.It is possible that a fault could occur as a result of local burning/arcing butno fault could be found under test. However a detailed visual inspectionshould reveal evidence of burning around the fault.
