Characteristics

*1. The indication of K thermocouples in the −200 to 1,300°C range, T and N thermocouples at a temperature of −100°C or less, and U and L

thermocouples at any temperature is ±2°C ±1 digit maximum. The indication of B thermocouples at a temperature of 400°C or less is

unrestricted. The indication of R and S thermocouples at a temperature of 200°C or less is ±3°C ±1 digit max.

W = (±0.5% of indication value (PV) or ±3°C, whichever is greater) ±1 digit max. PLII = (±0.5% of indication value (PV) or ±2°C, whichever is

greater) ±1 digit max.

The indication accuracy for K thermocouples in the

−199.9 to 999.9°C range

is (±0.5% of indication value (PV) or ±1°C, whichever is

greater) ±10 digit maximum. However, at a temperature of -100°C or less, it is ±2°C ±10 digit maximum.

*2. “EU” stands for Engineering Unit. The location of the decimal point depends on the type of sensor that is selected.

If the decimal point locations is set to 0 (****), however, it will be treated as if it were set to 1 (***.*).

*3. B, R, S, and W sensors: 0.2°C/Ω max. (100 Ω max.)
