使用條件
環(huán)境溫度：上限+40℃，下限-5℃，24h 內(nèi)平均溫度不高于+350℃。
海拔高度：不超過 2000m。
相 對 濕 度 ：空 氣 清 潔 ，相 對 濕 度 在 最 高 溫 度 為 + 40℃時不超過 50％；在較低溫度時允許有較高的相對濕度，例如+20℃時為 90％。但應考慮到由于溫度變化，有可能偶然產(chǎn)生凝露。
運輸儲存：-25℃至+55℃之間，在短時間內(nèi)(不超過 24h)可達+70℃，在這些極限溫度下裝置不應遭到任何不可恢復的損傷，而且在正常的條件下應能
正常的工作。
注：超出上述條件，請與本公司協(xié)商。
Operational Conditions
Ambient Temperature：Max：+45℃，Min：-5℃，+35℃ average over 24 hours ．
AItitude：≤2000m ．
Relative Humidity：Not exceed 50％ in clear air with the max. temperature of + 40℃ ; Higher elative humidity is permitted in lower temperature.For example, the relative humidity is 90％for the temperature of+20℃。But the variety of temperature should be taken into con- sideration because it's possible to condensate ．
Transportation and Storage: The temperature is be- tween - 25℃ to + 55℃ . In short time(not exceed 24h)the temperature can be + 70℃,In the limited tempera- ture，the equipment should not suffer nonrecoverable damage and in the normal condition，the equipment
should work normally ．
Not：If the condition exceeds the above，please consult
with our company ．
