NOTICE:
·

Hold the sensor only by its connector. Touching the sensing portion may change the resistance value.

·

When measuring, the sensor temperature must be the same as the ambient temperature.



HINT:

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


If the resistance is not as specified, replace the No. 1 cooler thermistor.
