CALCULATION EXAMPLES OF OVERALL ACCURACY
[Example] Input Range Pt 100 (JIS'97, IEC) RTD, 0 – 100°C,
Output Range 0 – 20 mA, Output Setting 4 – 20 mA
■ Overall accuracy
• Input Accuracy
1) Absolute value accuracy (Table 1): 0.15°C
2) 0.15°C ÷ 100°C × 100 = 0.15 %
3) 0.15 % > 0.1 % of span. ➠ 0.15 % is selected.
• Output Accuracy = Output Range Span (20 mA) ÷ Output Span Setting (16 mA) × 0.04 % = 0.05 %
Overall Accuracy = 0.15 + 0.05 = ±0.2 %
