• Enter the temperature within the input

• Set the values so that the sensor two-
point correction offset value (measured
value) is smaller than the sensor two-
point correction gain value (measured
value) and the sensor two-point
correction offset value (corrected value)
is smaller than the sensor two-point
correction gain value (corrected value).
