6.3.2 MONOTONIC OPERATION

Monotonic operation means that the device’s

resistance increases with every step change (from

terminal A to terminal B or terminal B to terminal A).

The wiper resistance is different at each tap location.

When changing from one tap position to the next (either

increasing or decreasing), the ΔRW is less than the

ΔRS. When this change occurs, the device voltage and

temperature are “the same” for the two tap positions.
