*1. Based on characteristics of K-type thermocouple and radiation rate of 0.98.
*2. The accuracy is given as the change in temperature from any reference temperature of the sensing object. For
       example, if the reference temperature is 50°C, the accuracy at 55°C would be ±2% PV or ±2°C, whichever is larger
       and the accuracy at 60°C would be ±4% PV or ±4°C, whichever is larger.
