12-6) Table of temperature sensor according to resistance and voltage conversion.
The input voltage to the MICOM PORT could be different by a hardware. This is a table based on the
voltage using the 10kohm-F.
MICOM PORT voltage when the sensor is open: about DC 5V(Vcc LEVEL)
MICOM PORT voltage when the sensor is shorted: about DC 0V(Ground LEVEL)
