PERFORMANCE
Conversion accuracy
(in percentage of input range)
±0.1 % (@ input range -20 - +20 mA)
Conversion accuracy is inversely proportional to input span.
Conversion accuracy computation example:
When input range is 4 - 20 mA: conversion accuracy = nominal input span (40 mA) ÷ input span (16 mA) × 0.1 (%) = 0.25 (%).
Nominal input span is the same as the span at input range
-20 - +20 mA DC.
