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