  1. Measure the resistance.

    Standard resistance:
    Tester Connection
    		Condition
    		Specified Condition
    1 - 2
    		10°C (50°F)
    		3.00 to 3.73 kΩ
    1 - 2
    		15°C (59°F)
    		2.45 to 2.88 kΩ
    1 - 2
    		20°C (68°F)
    		1.95 to 2.30 kΩ
    1 - 2
    		25°C (77°F)
    		1.60 to 1.80 kΩ
    1 - 2
    		30°C (86°F)
    		1.28 to 1.47 kΩ
    1 - 2
    		35°C (95°F)
    		1.00 to 1.22 kΩ
    1 - 2
    		40°C (104°F)
    		0.80 to 1.00 kΩ
    1 - 2
    		45°C (113°F)
    		0.65 to 0.85 kΩ
    1 - 2
    		50°C (122°F)
    		0.50 to 0.70 kΩ
    1 - 2
    		55°C (131°F)
    		0.44 to 0.60 kΩ
    1 - 2
    		60°C (140°F)
    		0.36 to 0.50 kΩ
    NOTICE:
    1. Touching the sensor even slightly may change the resistance value. Hold the connector of the sensor.
    1. 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.
