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.

Output Accuracy: ≤ ±0.04 %

[Example] 10000 μV span input, 1 – 5 V output

Custom input Accuracy = 5 ÷ 10000 × 100 = 0.05

Output Accuracy = 20 ÷ 4 × 0.04 = 0.2

Overall Accuracy = 0.05 + 0.2 = ±0.25 %
