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.
-
Use a thermometer to detect the ambient temperature of the installation area around the cooler thermistor (ambient temperature sensor).
HINT:
As the temperature increases, the resistance decreases (see the graph).
-
If the result is not as specified, replace the cooler thermistor (ambient temperature sensor).
