Always used Megger mft, but the company I'm working for at the mo' use Fluke, hence the title. I was testing for Ze, well Zdb really and got Error 4. I can test again in the morning on another meter, just curious.
thanks in advance
 
Yeh had the same problem years ago with one, sounds like a poor connection. Hated the meter with a passion, ended up just randomly packing in one day and got told it would cost around £600 to fix, my boss only paid £550 for it in the first place!!
 
[FONT=&amp]The Error 4, Fault Voltage, message is often triggered by a 'phantom fault voltage' caused by poor contact between one or more test probe(s)/crocodile clip(s) and the test point, usually either E and/or N, remake test connections and re-test. [/FONT]
[FONT=&amp] If the Error 4 message persists then you actually have a fault voltage present on the circuit that needs to investigated and eliminated before re-testing. [/FONT]

The re-wire is 20 onebed flats, in a block. All other tests were hunky dory, I will follow up what you say, as it is a sub main from the (30 year old?) 3 phase, using the old tails(16mm), new 10 mm earth (at least 10m run to my db) but as I said, the test leads were like yesterdays spaghetti, cheers Markie, thanks for taking the time to respond.
 
our fluke does this on nearly all tt systems, anything over about 10 ohms seems to do it. cant blame it on earth faults either because we were still getting it with main switch off and earth rod disconnected from installation.
