1. Power Rating between the wiper terminal R
2. Absolute Linearity is utilized to determine actual wiper resistance versus, expected resistance = (R
3. Relative Linearity is a measure of the error in step size between taps = R
4. 1 Ml = Minimum Increment = R
5. Typical values are for T
6. This parameter is periodically sampled and not 100% tested.
