ABSTRACT:
An electronic thermometer is provided in which the number of pulses counted in a first count and the number of pulses counted in a second count are respectively proportional to the resistance of a reference resistance and that of a thermosensing element. When the first counted value is to be adjusted so as to realize the absolute value adjustment of the thermometer, the difference between the resistance of the thermosensing element and the resistance of the reference resistor is adjusted by varying the number of counts in a counter upon whose content the timing of the second count depends. Accordingly, the absolute value precision adjustment of the electronic thermometer is realized by providing an initial logic adjustment circuit in which the number of the first clock counts is appropriately varied.
