Note 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.
