INSPECTION

PROCEDURE

1. INSPECT THERMISTOR ASSEMBLY

(a) Check the resistance.

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

Standard resistance:

Tester Connection	Condition	Specified Condition
1 - 2	10°C (50°F)	3.00 to 3.73 kΩ
	15°C (59°F)	2.45 to 2.88 kΩ
	20°C (68°F)	1.95 to 2.30 kΩ
	25°C (77°F)	1.60 to 1.80 kΩ
	30°C (86°F)	1.28 to 1.47 kΩ
	35°C (95°F)	1.00 to 1.22 kΩ
	40°C (104°F)	0.80 to 1.00 kΩ
	45°C (113°F)	0.65 to 0.85 kΩ
	50°C (122°F)	0.50 to 0.70 kΩ
	55°C (131°F)	0.44 to 0.60 kΩ
	60°C (140°F)	0.36 to 0.50 kΩ

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 thermistor assembly.

HINT:

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

If the specified condition is not met, replace the thermistor assembly.
