*1. The accuracy depends on the sensors used and the measurement temperatures. For details, refer to the user's
       manual.
*2. This is for an external power supply, and not for internal current consumption.
*3. L and −100°C or less for K and T are ±2°C±1 digit max., and 200°C or less for R and S is ±3°C±1 digit max. No
       accuracy is specified for 400°C or less for B.
