Which tester are you using to do the tests?

 

[ezzzekiel]

sounds like you are carrying out test incorrectly as amp says "what tester" but generally l,n.e connected and switch on unless calculating via Ze+R1+R2

buy a copy of guidance note three.

 

[Amp David]

A very valid point, but also reading the meter instructions is a good start also.

"No line" sounds like there is no power to the point at which you are testing???
