Measure the resistance between terminals. If the actually measured value is approximately
equal to the checker value, it means that the sensor is normal.
For the resistance/temperature characteristics of various sensors, see page 225 [Table7.3 List
of resistance/temperature characteristics of outdoor unit sensors].
