操作方式
將實驗室所有的氣窗打開 將前導板放下來 將後導風板放下來
先放下第一片後再放第二片 前導板放下完成圖 後導板放下完成圖
將待測物架設在固定支架並鎖緊 將測速器電源開啟並設定RS232模式 實驗室裡一切就緒後兩扇防風門都應鎖緊
將實驗室總電源開啟 變頻器開啟前請先將風力調節鈕歸零 開啟後可在螢幕看到風力測試值
一開始運作前要先檢查所有安全事項,啟動前請先確定風力調節鈕要先歸零,啟動後再慢慢增加風力請勿暴衝增加,一但實驗啟動嚴禁人員運作中進入實驗室以免發生危險。
 
雨水酸雨實驗
 

在化學上定義水之pH(酸鹼)值等於7為中性,>7為鹼性,<7為酸性 )自然大氣中含有大量二氧化碳,二氧化碳在常溫時溶解於雨水中並達到氣液相平衡後,雨水之酸鹼值約為 5.6,因此大自然的雨水是酸的,所謂「酸雨」認知為當雨水酸鹼值在 5.0 以下時,即確定受到人為酸性污染物的影響視為酸雨。

實驗範圍:一般性的防水測試與酸雨測試

 
請先將抽水馬達總開關開啟 打開抽水馬達避免雨量太大排水不及 出水要先選擇雨水或是酸雨測試
抽水選擇必須與出水相同以免混淆 將待測物架設在固定支架並鎖緊 開啟後再依客戶需求實驗
