*Determining the temperature correction value
Temperature detection characteristics formula

Ambient temperature (
Hence, TEMP input AD value = (463 - Ambient temperature)/2.876
The reference temperature (+23.6

by '1', temperature is determined.
For temperature correction, the input AD value is +/- inverted.
