1. Process temperatures above 185 °F (85 °C) require de-rating the
ambient limits by a 1.5:1 ratio.
2. 220 °F (104 °C) limit in vacuum service; 130 °F (54 °C) for pressures
below 0.5 psia.
3. Reference conditions are 70 °F (21 °C), Stable operating pressure
with periodic changes, transmit rate of once per minute, and routing
data for three additional network devices.

A.2.7 Minimum span limits for percent of
range engineering unit
The maximum rangedown is 10:1. The device maintains
reference accuracy specification up to 6:1 rangedown. After
6:1 rangedown the reference accuracy decreases to 1% of
span.
