The idea is that you want the arm to be at the level you would for playback; measure the downforce with the arm higher or lower than at the record height and the measurement will be either higher (stylus below record height) or lighter (arm measured above the record's height).
Think of the arm as a balanced lever- if it leans either way from level (meaning exactly where you want the stylus to sit, which would be record height) at its fulcrum's point of balance, it will exert more force in that direction. Hence you need to take your measurement at the record height.
Hope I used the right terminology there!
