K-type thermocouples have positive and negative poles

When wiring a K-type thermocouple, pay attention to the positive and negative polarity: the red wire is the positive pole (+), and the gray/white wire is the negative pole (-). Reversing the connection will cause abnormal temperature readings or prevent acquisition.
