  1. Partially soak the sensor in the water and warm up the water.

  1. Measure the resistance between the terminals.

    Standard resistance:
    Condition
    		Specified Condition
    Approx. 20°C (68°F)
    		2.32 to 2.59 kΩ
    Approx. 80°C (176°F)
    		0.310 to 0.326 kΩ
    If the result is not as specified, replace the sensor.
    NOTICE:
    When checking the sensor in the water, keep the terminals dry. After the check, wipe the sensor dry.
