Sensor resistance characteristics table

Resistance value allowance of sensor is ±5%.

When measuring the resistance value of the sensor, allow the temperature of that sensor to stabilize for at least 3 minutes
before measuring. This delay is necessary because of the sense speed relationship.

Use a digital tester to measure the resistance. An analog tester has to great a margin of error.

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.

Resistance of the freezing sensor shall be measured with a digital tester after separating CON7 of the PWB ASSEMBLY
and the MAIN part.
