Environmental effects

Hazardous area classifications

Ambient temperature limits Operating and storage: –40 to +140 °F (–40 to +60 °C)

Below –4 °F (–20 °C), LCD responsiveness decreases and LCD may become difficult to

read. Above 131 °F (55 °C), some darkening of the LCD panel

might occur.

ATEX requires limiting ambient temperature to below 131 °F (55 °C).

Humidity limits 5 to 95% relative humidity, non-condensing at 140 °F (60 °C)

Vibration limits Meets IEC68.2.6, endurance sweep, 5 to 2000 Hz, 50 sweep cycles at 1.0 g
