M3LDY OPERATING MANUAL EM-2664-B Rev.0

12.1.9  CALCULATION EXAMPLEs OF OVERALL ACCURACY

Input 4 – 20 mA, Output 4 – 20 mA 

Input accuracy = Range 20 mA ÷ Span 16 mA × 0.06% = 0.075% 
Output accuracy = Range 20 mA ÷ Span 16 mA × 0.04% = 0.05% 

 Overall accuracy = 0.13% 

(Segment gain ≤ 1.  Multiply the calculated result by the gain when exceeding 1.)
