ABSTRACT:
A temperature probe conditioner, while developing a voltage output proportional to probe temperature, generates a verify and a calibration output. A verify output to check the correctness of the conditioner's output voltage and a calibration output to confirm the range of the conditioner as well as to calibrate the port of an external circuit. These signals are connected to a microprocessor or similar device which makes decisions on whether to turn cooking elements "on" or "off" or to stop due to detected errors.
