Paul.m i (mostly) rewired a god awful dogs dinner of a mess of a hairdressers 3 years ago, all manner of problems.

hairspray in the smoke alarms was the best

when I got there, there was almost no insulation on the Neutral from the meter, no gas or water bond, the 'plumber' had been in and fitted a couple of sinks and disconnected a spare shower...by simply snipping the 6.0mm2 T+E and left it resting (live) on the water pipe.

and the list goes on

The MFT 15nn have an analogue needle, as well as the numeric display, which hasa scale up to 1000 MOhm and then to infinity, but not beyond.

And what does ''Infinity'' mean on a IR meters megohm range?? Not a lot basically, it just means beyond the range of measurement of the meter you are using.
