Note:
Accuracy values are stated for an operating temperature
between 64° and 82°F (18° and 28°C). All accuracy specifications
must be derated (increased) by 5.5% for each degree F of operating
temperature outside this range.
For example, an accuracy specification of ±3% between 64°F and
82°F would be derated to:
