ASC tube trap: which's reflect or absorb side?


Hi,
Just having a few tube traps but don't know where is the starting and end point of relect or absorb side. I know that half of the trap is reflect, and the orther half is absorb but don't know where to start with.
Thanks for your help!

Ramses' answer is my recollection with my old tube traps, which did not have the button Fmpnd mentions.
