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).
