1) 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
• Resistance of the freezing sensor shall be measured with a digital tester after separating CON7 of the PWB ASSEMBLY
and the MAIN part.
