*
Independent Linearity is the deviation in percent of the
total measured resistance of the actual resistance at
any point, from the best straight line drawn through the
resistance at any point, from the best straight line drawn
through the resistance vs. rotation curve. The slope and
position of the line can be adjusted to make these deviations
minimum.
