POTENTIOMETER CHARACTERISTICS
Notes: 1. Power Rating between the wiper terminal R
Notes: 2.Absolute Linearity is utilized to determine actual wiper resistance versus, expected resistance = (R
Notes: 3.Relative Linearity is a measure of the error in step size between taps = R
Notes: 4.1 Ml = Minimum Increment = R
Notes: 5.Typical values are for T
Notes: 6.This parameter is periodically sampled and not 100% tested.
