Maybe because my Supernova Plus (Qty 2) sits steadily on the trolley all day during testing is probably the reason I've not hat the problem with the 110v transformer as mentioned above - in my eight years of use.
(Having said that with a firm hold on the wooden table leg!! & clutching my lucky rabbits foot. etc etc.)
A lot to be said for the trolley!
Another good point with the seaward kit I didn't mention before is the memory. Had one with melted boards terminal damage once but the test data could still be recovered by Seaward - saved more than cost of tester!
Moral of that story was never drop loose fuses or paperclips in the casing 'pocket'!
