fluke 1664fc tester

Fred
Hello. Does anyone have a fluke 1664fc tester, and have problems with it ? Most times I use it, it comes up with error message 5, which I think is interference on a circuit. Had the tester a couple of years now. Starting to wish a had bought a megger. It also trips rcds out, spoke to Fluke technical and their response was its a very complex tester, that's when technical is open, as apparently technical is closed on Tuesdays, as its the chaps day off !!!

    Error code 5

    Excessive Noise

    Turn off all appliances (Loop, RCD measurements) or move the earth stakes (earth measurement).

    So the same as the icon with a spike on a wave I am used to seeing on my Megger testers indicating a possibly less than accurate result due to installation conditions rather than a fault with the tester.


    It was trying to get reliable loop test results under less than perfect conditions on less than perfect installations that led me to buying a Megger two wire loop tester

    The downside of the dedicated two wire tester is it is slow, oh, so slow. Having said that it appears that the full test time for a lo-3 wire test on the Megger MFT1741 is three minutes 


    So having thought that when I bought my new MFT that can do lo-2 wire loop tests I would be getting rid of the dedicated no trip 2 wire tester, it looks like I will be keeping it.


    Regards the original post it looks like you will have to spend more time testing disconnecting loads and other circuits or try a different tester.
