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