NOTES:
1. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage = (V_w(n)(actual) - V_w(n)(expected)) = ±1 Ml Maximum.
2. Relative linearity is a measure of the error in step size between taps = V_{W(n+1 )} -[V_w(n) + Ml] = ±0.2 Ml.
3. 1 Ml = Minimum Increment = R_TOT/15.
