HOW TO CALCULATE THE ACCURACY
■ Overall Accuracy
[Example] Pt 100, 0 – 700°C, 1 – 5 V output
Input Accuracy
= Max. Range ÷ Input Span × Input Accuracy
= 1050 ÷ 700 × 0.02
= 0.03
Output Accuracy
= Max. Range ÷ Output Span × Output Accuracy
= 20 ÷ 4 × 0.02
= 0.1
Overall Accuracy
= 0.03 + 0.1
= ±0.13 %

Accuracy with a User’s Temperature Table
Custom input accuracy + output accuracy
(Inversely proportional to the span)
Input Accuracy
:
(a) Ω ÷ Input Span × 100 %
where (a) is 100mΩ or [Max. Range × 0.2 %], whichever is greater.
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] 100 – 200 Ω input, 1 – 5 V output
(a) is the greater value among: 200 Ω × 0.2 % = 400 mΩ, or 100 mΩ, thus 400 mΩ is selected.
Input Accuracy = 400 mΩ ÷ 100 Ω × 100 = 0.4
Output Accuracy = 20 ÷ 4 × 0.04 = 0.2
Overall Accuracy = 0.4 + 0.2 = ±0.6 %
