Charging up small paper capacitors with the insulation tester (500V DC) and then leaving them lying around for unsuspecting apprentices to "fetch for me please" was a favourite trick when I was an apprentice and later when I wasn't  

 

Health and Safety what's that?

 

I also had some lengths of sleeving with crocodile clips on the end, hours of fun watching the poor lads trying to fault find their circuits.

 

The good old days.

I've got a Habotest unit on order, should be here Saturday, I'll report on it's operation.

 

Tester has arrived, works fine, seems to be well put together, the N-E voltage meter is a handy addition (4V between the TN-C-S house earth and the TT car-port earth).

 

Only minor issue is that the RCD test button needs a good press to make it work, but it has an LED so if the lights and the RCD doesn't trip you have a problem.

Does it check the "polarity" correctly without a ground if you use an appropriate adaptor?

No, it just indicates "open ground", but that's not really surprising. You can use a simple neon screwdriver on your 2-pin outlets.

 

It also can't detect N-E swapped, although in this case plugging in any load would trip your RCD/RCBO anyway. I've not tried it but I suspect the RCD test wouldn't trip the RCD in this case.

Hi Crossy. So you'de recommend it?

I reckon so, it has the correct plug and RCD test current and reads outlet voltage, frequency and N-E voltage (could be handy).
