In the end I got the Martindale EZ2500 as opposed to the EZ150, it gives a more accurate read out, anyways it arrived today so I gave it a go, looks well made as does the IEC lead and the carry case.
So....re connected the earth rod to the earth terminal in the chalet, plugged in the loop tester and powered up, readings displayed at the chalet are given below:
Mains supply = 241 vac @ 49.9 hz.
Phase earth loop impedance = 61.5 ohms, PFC = 4 amps, that's not too bad for a first attempt with the earth rod.
Phase neutral impedance = 0 .44 ohms, PS(S)C = 525 amps, I'm happy with that.
For the relatively low cost of a couple of earth rods/connector etc I think I'll try and sink another earth rod down to 2.4 meters about 3 metres from the one I put in the other day, connect them up and see how much the 61.5 ohms is reduced.
For the above test all SMPS's in the house and chalet were disconnected.
The camera is in use by Mrs at the mo' I'll try and post some pics tomorrow.
