Don't meters compensate for their own resistance / leads etc ?

No, as has been stated, the com (black) and the VOmh (red) need to be shorted by touching them, this will give you the resistance of the leads. Subtract this from the reading you get between the screws.

eg, my meter reads 0.4ohms shorting the leads. A reading between the pos and neg screws on my atty is 1.9ohms so my coils is 1.5ohms.

He's gone very quiet!
Oh well, he'll have another story to tell the grandkids.

Nooooo im still alive   I touched the 2 probes together on the settings advised and it read 0.4 so i checked a base i had with a coil on it and it reads 2.00 ohms so taking the 0.4 away should give me a 1.6ohms ressistance thew that confused me lol.
Then i checked my base with the coil on it on my MVP and BINGO it reads 1.6ohms so spot on.


I also checked the ressistance between the 2 screws with the coil fitted and it was the same.
 
Dont think the misses is to happy though i rolled in from the garage at 10pm to a waiting face of thunder oppps

Thanks to everyone for your replies and help as allways very helpfull

Much appreciated
