In the old days a table manual always said to adjust the VTF to the mfg specs than use the same setting for anti-skate. Problem being that neither of the dials were very accurate.
I use a test record but you can also come close by looking at the stylus/cantilever head on through a magnifying glass while playing a record. Check to see if it is perpedicular to the record or if it is leaning one way or the other. You can use the edge of the cartridge as a guide if you KNOW that the edges are perpendicular to the headshell and the azimuth is dead on. Otherwise, try to see if it is straight up and down to the record and then dial it in by ear.
