CALCULATION EXAMPLES OF OVERALL ACCURACY
[Example] Input Span 60°, Output Range 0 – 20 mA, Output Setting 4 – 20 mA, Segment Gain 1.5
■
Overall accuracy
• Input Accuracy = Input (60°) × Input Accuracy (0.2 %) = 0.12°
0.12°< 0.5° thus
Input Accuracy = 0.5° ÷ 60° × 100 = 0.83 %
• Output Accuracy = Output Range Span (20 mA) ÷ Output Span Setting (16 mA) × 0.06 % × Segment Gain (1.5) = 0.1125 %
Overall Accuracy = 0.83 + 0.1125 = ±0.9425 %
