Notes:

(1) Absolute Linearity is utilized to determine actual wiper voltage versus expected voltage

= (Vw(n)(actual) – Vw(n)(expected)) = ±1 Ml Maximum.

(2) 1 Ml = Minimum Increment = RTOT/31.

(3) Relative Linearity is a measure of the error in step size between taps = VW(n+1) – [Vw(n) + Ml] = +0.2 Ml.
