Hi All
DO NOT RELY ON THE SWA WIRE SHEATHING FOR EARTHING TO AN OUTBUILDING !!!!
Disconnect one end of the sheathing and use it only as an earth protection for the feed cable. Then provide a dedicated earthing method for the out building.
It is unlikely the steel sheathing will give you an acceptable test result.
See the Dave Ward videos on TT
Obviously you can't use the sheath, it's made of plastic!
There's no reason you can't use the steel armour of the cable though, that's one of the things it is designed to do!
The steel armour will give you perfectly acceptable test results if it is installed correctly.
