Title:
TEMPERATURE MEASUREMENT INSTRUMENT, TEMPERATURE CONTROLLER, AND SHORT-CIRCUIT IDENTIFICATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/087915
Kind Code:
A1
Abstract:
The present invention makes it possible to detect a thermocouple short circuit without outputting to an object of temperature control by determining, during a period when the temperature around the terminals that the thermocouple is connected to is changing, whether there has been a change in the electromotive force of the thermocouple corresponding to the temperature change (S301–S304) and determining that there is a short circuit if it has been determined that there has been no change in the electromotive force of the thermocouple corresponding to the temperature change (S304→S306).
