Note: 1. The indication of K thermocouples in the -200 to 1300°C
range, T and N thermocouples at a temperature of -100°C
max., and U and L thermocouples at any temperature is
±2°C ±1 digit maximum. The indication accuracy of the B
thermocouple at a temperature of 400°C max. is not
specified. The indication accuracy of the R and S
thermocouples at a temperature of 200°C max. is ±3°C ±1
digit max.
2. “EU” stands for Engineering Unit and is used as the unit
after scaling. For a temperature sensor, the EU is °C or °F.
