There has been a lot of discussions about this on different forums and people built weighing systems to measure the SW as shown on this pictures.
Only one scale is ok but we found out that Head does the same measurements with 2 scales which is easier of course.
this method does not measure the swingweight. It measures the balance. You can than use the measured balance, weight, and the length to --approximate-- the swingweight. Depending on how the weight is distributed on a given racket the swingweight approximation will vary (sometimes it will be fairly accurate, sometimes not so much. For non-customized rackets it will be likely pretty good approximation).
But to be technically exact you cannot measure the swingweight that way
