9.接線必須正確(que)，一定要進行接地。不接地可能(neng)造成觸電、錯(cuo)誤動作事故、顯示不正常或(huo)測(ce)量有(you)較(jiao)大誤差。

10.定(ding)期(qi)檢(jian)查端子(zi)螺絲和固定(ding)架(jia)，請不要在松動的情況下使用。

11.儀表運轉期間(jian)，電源入力端子蓋必須(xu)安裝(zhuang)在端子板上(shang)以防觸電。

12.儀表(biao)在運轉中，進行修改(gai)設(she)定、信號輸出、啟動(dong)、停止等操作(zuo)之前(qian)，應(ying)充分地考慮安全性，錯誤的操作(zuo)會使工作(zuo)設(she)備損壞(huai)或(huo)發生故障。

13.請使用(yong)干布擦拭儀表，不要(yao)使用(yong)酒精(jing)或其他有機溶液，恒(heng)(heng)溫恒(heng)(heng)濕(shi)試(shi)驗箱生產廠(chang)家，不要(yao)把水濺到儀表上(shang)，如果儀表浸入水中(zhong)，請立即(ji)停止使用(yong)，否則有漏電、觸(chu)電或火(huo)災(zai)的危險。

14.儀表內部零件有一定的壽命期限，為持續安全地使用本儀表，請定期進行保養和維護。報廢本產品時，請依工業垃圾處理。
