Abstract
An ear thermometer is tested at the time of manufacturing calibration for determining a temperature coefficient to be stored in information storing means. Based on the temperature coefficient, signal processing means compensates an undesirable temperature deviation caused by a change of an ambient temperature upon temperature taking, thereby enhancing the accuracy of the ear thermometer. Also, a method is provided for calibrating the ear thermometer by determining the temperature coefficient without increasing additional cost and calibration procedures.
