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

  • Standard resistance:
  • Tester ConnectionConditionSpecified Condition
    J38-1 - J38-210°C (50°F)3.00 to 3.73 kΩ
    J38-1 - J38-215°C (59°F)2.45 to 2.88 kΩ
    J38-1 - J38-220°C (68°F)1.95 to 2.30 kΩ
    J38-1 - J38-215°C (77°F)1.60 to 1.80 kΩ
    J38-1 - J38-230°C (86°F)1.28 to 1.47 kΩ
    J38-1 - J38-235°C (95°F)1.00 to 1.22 kΩ
    J38-1 - J38-240°C (104°F)0.80 to 1.00 kΩ
    J38-1 - J38-245°C (113°F)0.65 to 0.85 kΩ
    J38-1 - J38-250°C (122°F)0.50 to 0.70 kΩ
    J38-1 - J38-255°C (131°F)0.44 to 0.60 kΩ
    J38-1 - J38-260°C (140°F)0.36 to 0.50 kΩ
  • NOTICE:
Hold the sensor only by its connector. Touching the sensor 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).

If the resistance is not as specified, replace the room temperature sensor.
