摘要： Method of testing a sensor device that comprises a single angle calculator and at least two magnetic sensor elements, comprising the steps of: a) obtaining signals from the sensor elements; b) amplifying and digitizing the signals from the sensor elements; c) applying a first input value (IN1) derived from the digitized signal, to the angle calculator, to obtain a first angle value (α); d) applying a second input value (IN2) derived from the digitized signal, to the angle calculator, to obtain a second angle value (β); e) performing a consistency test of the first and second angle value (α, β); f) detecting an error of the sensor device or the angle calculator based on an outcome of the consistency test.

摘要： The present invention relates to an error detection circuit or detecting an error in a connection of an electrical component. The error detection circuit (10) comprises
- a control circuit (14),
- a terminal (16) arranged to connect the electrical component,
- a driving means (12), coupled to said terminal and arranged to be controlled by said control circuit,
whereby said driving means is arranged to drive a current on receipt of a control signal (Vctl) from the control circuit and whereby the control circuit is further arranged to receive in response to the current a measurement signal (15) via the terminal (16), to determine based on a characteristic of the measurement signal a possible error and to communicate an error signal based on said determining.-
