CALCULATION EXAMPLES OF OVERALL ACCURACY

[Example] Input Range Pt 100 (JIS'97, IEC), 0 – 100°C, Output Range 0 – 20 mA, Output Setting 4 – 20 mA

■ Overall accuracy

• Input Accuracy

100 ℃ × 0.1 % = 0.1 ℃

0.2 ℃ is higher thus 0.2 ℃ is selected

0.2 ℃ ÷ 100 ℃ = 0.2 %

• Output Accuracy = Output Range Span (20 mA) ÷ Output Span Setting (16 mA) × 0.06 % = 0.075 %

Overall Accuracy = 0.2 + 0.075 = ±0.275 %
