HOW TO CALCULATE THE ACCURACY ■ Overall Accuracy [Example] K, 0 – 1000°C, 1 – 5 V output Input Accuracy = Max. Range ÷ Input Span × Input Accuracy = 1640 ÷ 1000 × 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 % ■ Accuracy with a User’s Temperature Table Custom input accuracy + output accuracy (Inversely proportional to the span) Input Accuracy: 100 % × 5 μV ÷ Input Span The accuracy applies only at the user’s calibration points. Data between each point is approximated with a linear line, thus is not applicable.
