Any sparkies on here in or near Liskeard fancy poking at my 2009 reel? I don't have proper equipment but what I do have measures 1.8Ω for <50m of 1.5mm T&E, which is not reassuring.
E: Well a fresh battery later it's ~1.4, which is a little more likely.
The state of the electrical materials sold recently has just gone through the floor, might be time to get out of the trade or at least go back to working for someone else

mmm, one of the things i've noticed on many multimeters is that as the batteries run down they start to become very inaccurate long before they actually die. I suspect below a certain battery voltage the internal references stop working correctly.

I would not rely at all on the readings below say 3 ohms on the average multimeter, 2 of mine read somewhere between 0.4 and 0.8 ohms with one test lead linking the 2 sockets together.

Thats more to do with it being a niche product, with arse covering than accuracy though. Ordinary multimeters with good batteries are plenty accurate enough in the midranges it's just they don't tend to offer ranges below 200ohm so you are only using 1% of the full scale.
P.S. multimeter covers a huge range of devices, the ranges aglilent one on my shelf at uni also only goes down to 200 ohm but has no problem dealing with sub 1ohm values due to it's huge precision.
