CALCULATION EXAMPLES OF OVERALL ACCURACY
[Example] Input signal: 1 - 5 V DC, Output signal: 4 - 20 mA DC, Max segment gain with linearization set: 1.5
Input Range -5 – +5 V, Input Setting 1 – 5 V, Output Range 0 – 20 mA, Output Setting 4 – 20 mA, Segment Gain 1.5
Overall accuracy
• Input Accuracy = Input Range Span (10 V) ÷ Input Span (4 V) × 0.03 % = 0.075 %
• Output Accuracy = Output Range Span (20 mA) ÷ Output Span (16 mA) × 0.06 % × Segment Gain (1.5) = 0.1125 %
Overall Accuracy = 0.075 + 0.1125 = ±0.1875 %
