NOTICE:

• Touching the sensor even slightly may change the resistance value. Hold the connector of the sensor.

• When measuring the resistance, the sensor temperature must be 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 ambient temperature sensor.
