A daft question you may say, but, I was out last night with some Electrician friends for a few beers and a curry, the subject we were discussing was the safe isolation procedure.
An argument ensued about proving units and their operation, now my first test lamp was the Drummond, this was about 1973, I have had many different types over the years, but always thought the Drummond was the best by far. One of the lads said his Drummond had a self test facility, I couldn't quite believe that, but did argue to to forcibly as he is a good mate and he was adamant that he was correct, so we got back the serious question of whose round it was.
I guess my question is, and I'm quite sure I'm right they do not have a self test facility, has anyone any thoughts ?
