Standard Resistance:
Tester Connection Condition Specified Condition
1 - 2 -10°C (14°F) 7.30 to 9.10 kΩ
-5°C (23°F) 5.65 to 6.95 kΩ
0°C (32°F) 4.40 to 5.35 kΩ
5°C (41°F) 3.40 to 4.15 kΩ
10°C (50°F) 2.70 to 3.25 kΩ
15°C (59°F) 2.14 to 2.58 kΩ
20°C (68°F) 1.71 to 2.05 kΩ
25°C (77°F) 1.38 to 1.64 kΩ
30°C (86°F) 1.11 to 1.32 kΩ


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

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).
