A.1.5 Environmental requirements
Ambient temperature limits
• Operation: –40 to +140 °F (–40 to +60 °C)
• Storage: –40 to +140 °F (–40 to +60 °C)
Display responsiveness decreases, and display may become difficult to read, below –4 °F (–20 °C).
Above 131 °F (55 °C), some darkening of display may occur.
If possible, install the transmitter in a location that will prevent direct exposure to sunlight.
Different ambient temperature requirements may apply when installing the transmitter in a hazardous
area. Refer to the approval documentation shipped with the transmitter or available on the Micro
Motion web site.
Humidity limits
