Electric Underfloor Htg

[fraserd]

Hi, ive got a bit of an issue with some underfloor heating mat that i installed, all tested fine once laid, go back to 2nd fix and i have no continuity between L+N or E clear IRes between all cores its like its just a clean cut i.e a tile dropped on it but i cant point fingers. Tiles are all laid so i need to try and find the break somehow. Anyone any advice? had this problem before? i was looking at Hiring the Fluke 2042 but reviews seem a bit s**t. Cheers

That's what the manufacturers of mats I've connected up usually specify to validate the warranty.
