NOTE:
-

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.

HINT:  As the temperature increases, the resistance decreases (see the graph). 

If the result is not as specified, replace the sensor.
