50°C (122°F)

0.50 to 0.70 kΩ

H58-1 (+) - H58-2 (-)

55°C (131°F)

0.44 to 0.60 kΩ

H58-1 (+) - H58-2 (-)

60°C (140°F)

0.36 to 0.50 kΩ

NOTICE:

  • Hold the cooler thermistor (room temperature sensor) only by its connector. Touching the sensing portion may change the resistance value.
  • When measuring, the cooler thermistor (room temperature sensor) temperature must be the same as the ambient temperature.

HINT:

As the temperature increases, the resistance decreases (see the graph).

If the result is not as specified, replace the cooler thermistor (room temperature sensor).
