Notes on Humidity without Condensation For Wide Operating and Wide Storage Temp: Background color changes slightly depending on ambient temperature. This phenomenon is reversible. For Wide Operating Temp: Ta ≤ 70ºC: 75RH max Ta > 70ºC: absolute humidity must be lower than the humidity of 75%RH at 70ºC For Wide Storage Temp: Ta at -30ºC will be < 48hrs, at 80 ºC will be < 120hrs AND480320MST
