ok, well cheap compared to the likes of the Robin multi function boxes,
or a pile of separate testers.
Oh, better still ;-)
I was toying with the idea of "upgrading" my collection of standalone
Megger testers to a combined device, since some of my current ones have
some limitations (the continuity/insulation resistance tester only does
low ohms to 0.1 ohm resolution, the RCD tester does not have a ramp test
or the timer duration for testing time delayed RCDs, and the loop tester
does not have a non RCD tripping mode, or ability to read PSC/PFC
directly).
This one intrigues me:

What does the 17th edition introduce that will require tests not
currently supported on existing kit?
