- HINT:
- As the temperature increases, the resistance decreases (refer to the graph).
- NOTICE:
- Even slightly touching the sensor may change the resistance value. Be sure to hold the connector of the sensor.
- When measuring, the sensor temperature must be almost the same as the ambient temperature.
If the result is not as specified, replace the No. 1 cooler thermistor.
