Sorry, but I couldn't find the recommended tracking force for this cartridge. The most of the Stanton 500 cartridges here at the database are indicated with a tracking force from 2.0-5.0 grams, so I would give 2.0 grams a try.
Before you start to setup, you should pull the mains plug so the platter won't turn on if you move the tonearm. Then set antiskate to "0" and move the weight on the tonearm-tube in the direction of the arm-base in the first catch.
Move the tonearm from its rest and turn the counterweight till the arm is balanced (it is "hovering"). Move the tonearm back to the rest an set the weight on the tube in the following position (it should be the third catch):
The tracking force should be rd. about 2.0 grams now.
Now set the antiskate to "2"- by using the "spherical" scale. Finished!
