(2) How to calculate temperature
As shown in Figure 10-17, the temperature sensor detection value makes a characteristics curve that is linear
with respect to the temperature. Therefore, the temperature sensor detection value can be expressed with the
following expressions.

table data, and comparing them with the temperature sensor detection value during
temperature measurement. With this method, table data must be created for each interval
of temperatures to be detected.
