NOTES:

1. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage = (Vw(n)(actual) - Vw(n)(expected)) = ±1 Ml Maximum.

2. Relative linearity is a measure of the error in step size between taps = VW(n+1 ) -[Vw(n) + Ml] = ±0.2 Ml.

3. 1 Ml = Minimum Increment = RTOT/15.
