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
