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.
