摘要：
The invention is directed to a method of operating a tympanic thermometer, in which a sensor (8) for detecting infrared radiation is arranged in a housing (1) having a radiation inlet (23). Associated with the sensor (8) is an electronic evaluation unit (13). For temperature measurement, the radiation inlet (23) is covered with a probe cover (5) transparent to infrared radiation. The condition of a missing probe cover (5) is indicated by an audible warning signal or a signal lamp (14) which are activated after the thermometer is turned on.
