Sansui SR 717 Tone arm balance question


I am not familiar with this tone arm balance set up.
i don't see any anti skate adjustment.
.... I do see a round ring with numbers on it with a weight behind it that turns.
I can get the arm to float , however ,I do not know where to set the numbers.
This is different than my Technics SL 1600 which has anti-skate set ring 
How do I set the balance on this Sansui arm ?
Thank you
