Guy's,
There have been testers around to do this sort of test, for years.
I note that a number of two probe testers give a Phase Rotation reading on them, in the form of a circular arrow on an LCD screen.
Could someone please correct my way of thinking, in so much as,I was under the impression, to effect a decent 3 Phase Rotation test, you had to have a tester that would connect to and test all 3 of the phases.
The question I ask, is this, how can a 2 probe tester do the same job as a 3 Clamp tester?
