Having read the list of posts following Bobs note quoted above, I am a litt=
le bemused at the almost invective fuelled response in some of them.=20

Bob did say "Use extreme caution" and pointed at a reason for saying so.=20

But I would also point out that having a high quality meter isn't proof aga=
inst stupid use. This string of posts reminded me of a story told to me dur=
ing my apprenticeship, of a graduate engineer who decided to use his nice b=
right shiny new Avo 8 (arguably the highest quality multimeter available in=
 the post war years)to measure the impedance of the mains. Quite why he dec=
ided to do this is unknown, but he proceeded to turn the switches to the oh=
ms range and plugged the probes into the mains. The ensuing explosion was c=
ontained within the meter casing, but otherwise the effect was like that in=
 the pictures of the report Bob linked to above.

It seems no-one at uni taught him that the mains supply is about as close t=
o a perfect voltage source as you will ever see.
