Resistances vary with temperature and should conform approximately to the table below:

Temperature Range (°C)	Resistance Range
-30°C to -20°C	100.0kΩ - 190.0kΩ
-20°C to -10°C	57.0kΩ - 100.0kΩ
-10°C to 0°C	33.0kΩ - 57.0kΩ
0°C to 5°C	25.0kΩ - 33.0kΩ
5°C to 10°C	20.0kΩ - 25.0kΩ
10°C to 15°C	16.0kΩ - 20.0kΩ
15°C to 20°C	12.5kΩ - 16.0kΩ
20°C to 30°C	8.1kΩ - 12.5kΩ
30°C to 40°C	5.3kΩ - 8.1kΩ
40°C to 50°C	3.6kΩ - 5.3kΩ
