8.3 Temperature sensor resistance measurement method

Temperature sensor resistance measurement method (method of measuring the
resistance value of the compressor of the same, but is switched to the small resistance
of the interface unit).

Multimeter set to Ohms, according to the picture of the method of measuring the
resistance of the temperature sensor. According to the resistance table, the lower the
temperature the smaller the resistance.
