Resistor position nonlinearity error (R-INL) is the deviation from an ideal value measured between the maximum resistance and the minimum resistance wiper positions.
R-DNL measures the relative step change from the ideal position between successive tap positions. Parts are guaranteed monotonic. See the test circuit in Figure 28.

Resistor Terminal A, Terminal B, and Wiper W have no limitations on polarity with respect to each other.
7
Guaranteed by design and not subject to production test.
