Operating Temperature
(1)
(1) When the NT4 module detects 0°C (32°F) [(+/- 3°C) +/- 5.4°F] at the CJC, it will detect an out-of-range condition
and set values to downscale -270°C (-454°F). It is recommended that ambient temperature surrounding the SLC
500 system be maintained above 3°C (37.4°F) in order for the NT4 module to measure temperature correctly
without detecting an out-of-range condition.
0°C to 60°C (32°F to 140°F)
Storage Temperature -40°C to +85°C (-40°F to +185°F)
Relative Humidity 5% to 95% (without condensation)
