instructions:1- print that protractor on a A3 paper sheet (no adaptation at all) and check the AA' distances. Those distances MUST be equal to 140mm2- set AS force to zero3- the stylus must follow the arc - use the C and C' dots to ajust the effective length to its optimal value (229,128mm), when moving from C dot to C', you must not move the protractor on your platter4- once the effective length is correct, put the cartridge in the middle of the grid. Ajust the orientation of the cartridge: the cartridge body should be parallel to the lines of the grid. Check that you didn't modify the effective length...
