Hi tekkiesteve, its the Phase Earth loop linearity test part it says

Connect the tester to the 13 amp socket on the check box.

Connect the instruments bonded metal probe set to the instruments under test and note test reading with a probe applied to the green socket marked loop.

needs a little bit of explaining to me !!!!!

cheers

Phase L1 probe to to phase of socket outlet assuming you have a socket break out box,piggy back L2 neutral and L3 earth probe and insert into loop receptacle and test.Then remove L2/L3 probe and insert into loop 5R receptacle and test then compare the difference of the two readings with the check box cert on the back of the unit.
