The safe use of electrical work equipment at home (theiet.org)

I think the IET might not want to condone that give this case:
However, I too am surprised at the use of a picture showing an entirely inappropriate test being carried out for “in-service inspection and testing”.
Just to be clear, there's nothing wrong with this picture … for dead-test fault-finding (assuming, of course, the probe is not jammed up into the free outlet too tightly, on that I agree with Mike) - it does seem to be checking for continuity through the fuse.
BUT I'm fairly certain the IET CoP for In-Service Inspection & Testing of Electrical Equipment does not recommend the use of a multimeter on 20K range for continuity test of the protective conductor or protective circuit, as referenced in the caption on page 5.
