Beschreibung
Zusammenfassung:	A drug delivery system comprising drug expelling means and electronic circuitry with a sensor system adapted to determine an expelled amount of drug, the sensor system comprising a switch for actuating the sensor system between an off and on state. The electronic circuitry is adapted to actuate the sensor system from a high-power on-state to a low-power sleep state after a given amount of time to save energy, and, with the sensor system in the low-power sleep state, detect when the switch is actuated from the on-state to the off-state, this creating an error period. When an error period has been detected a display indicates to the user that the sensor system has been in an error state for a period of time corresponding at least to the error period.
