The invention relates to a method for monitoring a device (1) for internal state changes by means of a sensor (5) connected to the device (1). In order to configure such a method such that the method can be used to monitor the internal state of a device in a simple and reliable manner, use is made of a sensor (5) which, in the event of an internal state change of the device (1), directly experiences a colour change in the visible range of the light. In this case, the sensor (5) is connected to the device (1) in such a manner that the colour change thereof is visible from the outside. The invention also relates to an arrangement for monitoring a device for internal state changes. |
