I've been wanting to do this sort of test for a while and there was a
useful article about it in today's Independent.  As a result I
discovered that Maplin do a suitable measuring tool for £25 and I've
ordered one.  There's also an interesting looking gadget at
www.electrisave.co.uk, but that's rather more expensive.
