This item allows offset calibration of the temperature sensor.
Use <UP> or <DOWN> to add an offset to the temperature
measurement. -1.0 subtracts 1.0° from the reading, +1.2 adds
1.2° to the reading. Units depend on the range selected, either
°C or °F. The offset resets to 0.0 if the units are changed. The
range is -5.0 to +5.0 for °C and -10.0 to +10.0 for °F. Resolution
is 0.1°.
