2. Sensor resistance characteristics table
u
Resistance value allowance of sensor is ±5%.
u
In measuring resistance value allowance of sensor, perform measuring after leaving the sensor for more than 3 minutes
at the measuring temperature (delay is required due to sense speed relation relationship).
u
Since an analog tester has a large measuring temperature, measuring with a digital tester is required as possible as.
u
Resistance of the cold storage sensor 1 and 2 shall be measured with a digital tester after separating CON8 of the PWB
ASSEMBLY and the MAIN part.
u
Resistance of the freezing sensor shall be measured with a digital tester after separating CON7 of the PWB ASSEMBLY
and the MAIN part.
