A potentiometer (PT 1, PT 2 ) has a first terminal (A 1 ), a second terminal (A 2 ) and an intermediate tap (ZA), a resistor being between the first terminal (A 1 ) and the second terminal (A 2 ) irrespective of the position of the potentiometer (PT 1, PT 2 ). 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 1 ) and/or the second terminal (A 2 ) 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.
