Pretty much Guys,
A lot of these "Accidents" could be put down to lack of thought to the task at hand!.
I'm not meaning to sound silly about this, but, for what I have read over the last few postings, more testing of the test equipment, should have been performed, before it was connected to the "source under test", take a known LIVE supply and check your test equipment by that, simple Electrical Theory.
If I had my Live-Line Alarm (a Modie-Wark) anywhere near HV lines, I would check the darned thing, first at the voltage that I required it to work at, for a start, to make sure that the sucker worked.
Even with Low Voltage work, I always use a known source of Voltage to test the Integrity of my Duspol testers.
Life is far too short to go wasting it away on bad Voltage measurements, especially from 0-400V. [Linked Image]
