Sorry to butt-in here, but can you tell me how you measure earth rods?
What do you use to do the measuring, and what is the other test lead
connected to?

a) with a proper earth electrode testing kit, or

b) with a loop-tester, as John Rumm has already said (and this method is
endorsed by the On-Site Guide), or

c) my DIY cheat's method, see

Thanks for that :-)

You say...
"connect one end of the secondary
via a suitable length of wire to the main earth terminal in the house
and connect the other end to your earth electrode via an ammeter."

Do I assume this would be done with the rod disconnected from this main
earth terminal?

If so, if this is a TT installation, and there is no other path to earth in
the house (plastic water pipes etc..) how will you get a reading?

If not, surely this is only testing the cable between the rod and the earth
terminal (and your test cable!), not the rod it self?
