As the only means of testing an addition to your existing wiring?
Can I see the wordsit depends if they use the proper tester checking the earths impedance too...

printed on the front of that tester ? Hardly a full test of the socket.Does not detect Earth Neutral Reversal

Especially worrying if the installation is a TT system and a low impedance device when plugged in connects live to the CPC ( earth ) and the earth rod has dried out to become a high impedance.
Earth loop measurement, and socket faults, are all indicated with bright, long-life LEDs. This unit should be used as an indicator only and not to provide readings for completion of certificates.
Human error does exist during "the physical wiring up part". That is why there is a requirement for competance in the installer and full testing of all new circuits. And the same for existing circuits when a competant installer of equipment is using them for the electrical supply to the equipment he or she is installing.Why would earth and netral be reversed? The installer would have got that bit right with the physical wiring up part.
So speaks the guy with no electrical background.
For your info, it is not uncommon for the supplier to get Live and Neutral on the incomer the wrong way round.

yes it happens all the time Sorry but I have a copy of the 17th edition in my study. I was also tested on my knowledge in relation to the PAT testing certificate I hold which also covered socket testing.
