Abstract

PURPOSE: To enhance the handleability of a digital displayer indicating the data of set or measured temperature by using a system in which the displayer outputs a flashing signal in case where a temperature outside the controllable or indicatable range is set or detected.
CONSTITUTION: In setting or displaying a temperature by a temperature setting key 2, when the up key 3, for example, of the temperature setting key 2 is pushed, a micro computer 1 determines whether or not set data stored in a memory circuit B is the upper limit value of a controllable temperature range (or indicatable temperature range on digital displayer 10). In case where it is the upper limit value, the upper limit set data are displayed on the displayer 10 in a flashing manner. The flashing intervals are set up by a clock signal from a clock circuit C. On the other hand, in case where set data are not the upper limit value, 1°C is added to the set data of the memory circuit B, and the added result is displayed on the displayer 10. Even during the operation of down key 4, almost the same operation is conducted.
