6. Temperature Sensor
1) The sensor uses the characteristics of thermistor. If temperature goes higher, resistance goes
lower. On the contrary, if temperature goes lower, resistance goes higher.
2) MICOM input voltage is counted by sensor as follows.
(V
CC
: 5V, R
TH
: Sensor reisitance)
3) For the resistance information on temperature and MICOM input voltage, please refer the
conversion table. (Page. 41)
