PAT tests
Hi all,
I've just had an office PAT tested and to my surprise a number of newish (ie bout within the last 12-24 months) TFT monitors have 'failed'. The guy doing the testing has sort of shrugged his shoulders wehen I asked him exactly what this meant, and has recommended that I change the power leads - which seems daft as the power leads have been seperately checked and PASSED! Any idea what I should do? Should I replace the units and if so, what is likely to be the problem with them? Best wishes, Sky |

Best wishes, Sky What did they fail on, insulation or earth continuity? if the latter, what part of the monitor did the guy connect the crocodile clip to? -- Graham %Profound_observation% |

Do the monitors have external PSU's, or does the mains lead plug into them directly? I do wonder if the guy had the faintest idea what he was doing, if he just shrugged his shoulders when asked for details. A lot of PAT testers (most in fact) haven't got a clue. In future, I would suggest you ask to see the tester's C&G 2377/2 certificate before engaging them. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

I suspect this might be Capactive leakage coupling from the L and/or N conductors to the Earth line thats if they are kettle lead connected types!... -- Tony Sayer |

It may be that he's done an insulation test on the monitors without checking if they conform to BS EN 60950, and has destroyed them in the process. He might even have flash tested them. In either case, he should be paying for replacements. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |
