If it were that easy for a power meter to fail, electrical and electronic equipment all over Atlanta would be burning up every day. My point is that "fiddling" with equipment is functionally the same as making a mistake, only people make mistakes far more often they deliberately make fake results. People make mistakes every day all day long and yet our electrical equipment survives. - Jed
