CALCULATION EXAMPLES OF OVERALL ACCURACY

[Example] K thermocouple, 0 – 1000°C, 4 – 20 mA DC

output

Absolute value accuracy (Table 1): 0.25°C

CJC error (3°C) added: 3.25°C

• Input accuracy = 3.25°C ÷ 1000°C × 100 = 0.325 %

Output span: 16 mA (20 – 4)

• Output accuracy = 20 mA ÷ 16 mA × 0.04 = 0.05 %

Overall accucracy including CJC error = 0.325 + 0.05 =

±0.38 % of span
