Thanks for all your responses. They have confirmed my suspicions of how to align the cartridge. Here's why I was confused: The arm and turntable I have included the Clearaudio protractor, but there were no instructions for using it. I was confused because it only has a single null point printed on it.
Recently, I learned that I was missing the instructions for the protractor. There is no mention of its use in the instructions for setting up the arm. I found a manual online for the Unify arm which described the way to set up the protractor. Essentially, there are two lines within which you align the wand. Then you set up the cartridge at the single null point as you do with any arm. Why there's only one null point, I can't say.
Set up was finicky, for sure, but I got everything lined up properly and proceeded to trash the tip of the cartridge. First time that's happened in 40 years! So, one cartridge to Soundsmith and a spare installed.
All's good. Thanks again for all your help.
