Open the CIPO recordAbstract From the Canadian patent
A potentiometer (PT1, PT2) has a first terminal (A1) a second terminal (A2) , and an intermediate tap (ZA) a resistor being between the first terminal (A1) and the second terminal (A2) irrespective of the position of the potentiometer (PT1, PT2). 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 (A1) and/or the second terminal (A2) 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.
