This is the first time I've done a test on a TT system and I'm a bit stuck on the readings I am getting for loop impedence.
My Ze reading is 9.7 ohms which I think is ok(pretty sure I'm reading regs ok saying 21 ohms max)
The only thing is every reading I am getting from every circuit be it the end of the line or not is 2000 ohms.Its like it reads it and it just keeps giving me that.I am testing with a Fluke tester and there is no way to change the loop setting.
Now do I need to get another loop impedence tester with a setting selector or as I'm reading the regs---having a 100ma RCD protecting every circuit(as impedence reading is so high)is ok and I can just leave the readings I'm getting and write those down(this is a periodic inspection and report)
Any help would be great as NICEIC help line not much assistance thanks!
