HOW TO CALCULATE THE ACCURACY

Overall Accuracy
[Example] Total resistance 800 Ω, 250 – 750 Ω input, 1 – 5 V output
Input Accuracy
  = Max. Range ÷ Input Span × Input Accuracy
  = 800 ÷ 500 × 0.01
  = 0.02
Output Accuracy
  = Max. Range ÷ Output Span × Output Accuracy
  = 20 ÷ 4 × 0.02 = 0.1
Overall Accuracy
  = 0.02 + 0.1
  = ±0.12 %
