What meter are you using magill? Most modern low ohm meters should be capable of a resolution of 0.01

Edit: Thinking about it (I'm trying to work on my laptop as well as desktop, multitasking is not my strongest point) - Most meters have an intrinsic accuracy of about +/-0.05 ohms. So go with spinlondon's advice. We're trying to split the atom here. If shows zero you may have found the mythical superconductor.

It's good enough how do you get smilies on here?

Actually, thinking about it again (sorry to be boring) I have used my trusty Megger BMM503 to calculate the lenght of cable left on a reel, and it's pretty bloody accurate within a couple of metres.

Try measuring a length of 15mm copper pipe.

I use a tape for that spin!

 

[Deleted member 26818]

Is your tape in Ohms or Meters?

Ha ha - goodnight.

Right, i've now changed one of the leads and am now getting a reading of 0.5 ohms. (Using a Fluke multimeter).!!!

thats why! multimeters are no where near accurate enough!

Apologies, i meant to put multifunction - 1651. (Its been a long day!!)

What 'lead' have you changed? It's now reading 10 times higher than maximum allowable?

Beg or borrow a recently calibrated meter from a mate or test yours on a known resistance!
