Hi has anyone had this issue with their tester before ? when I test ze I get a good reading say 0.2 ohms. but when I test the zs of a circuit the reading is higher than it should be. if I know ze 0.2 and R1R2 is 0.2 . but ze may come out at 1 ohm and its not just this circuit. Then to see I tested at the load side of the rcd but all mcbs off and get 0.65 but ze is 0.2. its the same for both rcds on the board. faulty tester leads ???

Whats the resolution on the non trip setting on your tester? It might be way off what you might think acceptable (i know, i had one like this, it got retired)

Whats the make and model?
