The thermocouple always shows room temperature, but isn't changing when I warm up the thermocouple with a lighter: the AD597 chip is currently in self-measurement mode. If the + and - inputs of the thermocouple have a very low resistance, it will not give you the temperature of the thermocouple, but of the chip itself. Check this by placing a warm finger on the chip. If the value change quickly, this is indeed the case. Extend the thermocouple wires with terminal blocks or solder them together to get a higher resistance between the thermocouple inputs.
