Abstract
A potentiometer (PTPT) has a first terminal (A), a second terminal (A) and an intermediate tap (ZA), a resistor being between the first terminal (A) and the second terminal (A) irrespective of the position of the potentiometer (PTPT). In an evaluation method, a first drive voltage (GND) and at least one second drive voltage (VS), which is different than the first drive voltage, are applied to the first terminal (A) and/or the second terminal (A) and/or a third drive voltage (VS) is applied to the intermediate tap (ZA). The evaluation can be made from the different measurement voltages measured at the terminals.
