Hi guys,
Had an issue at a recent survey where doing a quick check and found we had pme with a reading of 0.44 ohms.
Called the network and they said they would send a guy around who promptly turned up and checked.
However his tester was giving a reading of 0.30!
I checked again using the same method he did and still got 0.44.
He said that he has found that some multi testers use the wrong range and we should be testing with a 20 ohm range and not 200 which apparently they are set at by default as otherwise it could be difficult to get a reading from a tt installation?
Anyone else had this?
I have dug out an old robin 4120dl that I used to use and that is still set at 20 ohm range from when I used to use it.
Might give that a hi in my place and compare but has anyone else had this?
