To test if there is some sort of earth present? A socket tester.

To test if the earth complies with the Wiring Regulations? An earth
loop impedance tester.

To do so correctly requires an earth loop impedance tester - an expensive
bit of kit - so in other words get a sparklette in if you suspect it's not
right and it's not just a broken or loose wire.

or do you mean test earth rod impedance. I suspect s/he means check
its connected, in which case a plugin socket tester is the way to go.
Buy for a fiver or make from plug & 3 mains neons.

My trusty universal AVO meter is no good then...

Absolutely not. An earth loop impednace tester is a specialist bit of
kit; that's all it does. Here's an inexpensive one, £295 plus VAT:

You can also hire one.
If your local hire shops don't have one there a few on the internet
who can mail it to you.

No. A proper test involves a fleeting high current short to earth and
measuring the current flow.

Very basic test to see if it's connected.
http://www.maplin.co.uk/module.aspx?...o=9800&doy=7m2

What exactly do you want to test?

The blurb for this says; "Check all new and existing mains installations
with this easy-to-use tester. Simply plug into any normal mains socket you
want to test. If everything is OK all three indicators light up. Other
sequences warn of specific problems such as Live and Neutral reversed, no
Earth, etc".

Or something more advanced?

Not to give it a proper test, which must be done at high current to
check that there is no bit of the wiring which will fail if the high
current of an earth fault flows.

Your meter will only do a low current test. It is no better at
indicating the condition of the earth than a socket tester.

The question remains the same, what precisely do you want to test?

The plug socket for the dishwasher, as it's 'popped' and tripped out twice.
I think it's the dishwasher though but wanted to check the socket myself.

For that money you can just about get a minimal 16th tester which will do
conitinuity, insulation, earth loop and rcd testing.
