  1. Measure the resistance according to the value(s) in the table below.

    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
    HINT:
    As the temperature increases, the resistance decreases (refer to the graph).
    NOTICE:
    1. Even slightly touching the sensor may change the resistance value. Be sure to hold the connector of the sensor.
    2. When measuring the resistance, the sensor temperature must be the same as the ambient temperature.
    If the result is not as specified, replace the cooler thermistor (room temperature sensor).
