Much better video, nicely done.
Stop being so defensive, both are good meters, not network analysers, but both work at the job well enough to tell bad, from marginal, from pretty good. At least it enables you to tell the not bulging and popped dud from the not bulging and still working one. If the case is looking like it is a balloon, or the sleeve is split or shrunk down on the side you can tell it is dying or past dead, only waiting to go bang.
