PERFORMANCE
Conversion accuracy
(in percentage of input range)
±0.05 % (@ input range -10 - +10 V)
Conversion accuracy is inversely proportional to input span.
Conversion accuracy computation example:
When input range is 1 - 5 V: conversion accuracy = nominal input span (20 V) ÷ input span (4 V) × 0.05(%) = 0.25 (%).
Nominal input span is the same as the span at input range
-10 - +10 V DC.
