If any portion of the temperature sensor circuit
fails, the thermometer display will self-diagnose the
circuit. An “SC” (short circuit) will appear on the display
module in place of the temperature when the
sensor is exposed to temperatures above 55°C
(131°F), or if the sensor circuit is shorted. An “OC”
(open circuit) will appear in place of the temperature
when the sensor is exposed too temperatures below
-40°C (-40°F), or if the sensor circuit is open.
