能迅速準確地實現負荷的數字標定,具有過載保護功能;

試驗條件(試樣環境、測試條件)可編程;

具有儲存試驗結果,并能查閱和遍歷試驗過程的功能;

曲線坐標自動調整功能:進入測試狀態,系統自動調整坐標值,在整個測試過程中,始終是完整的曲線。試樣條件可自動存儲,自動調出,也可再設定;

數據拾?。涸囼炌戤吅笤谠囼炃€上可用鼠標拾取數據。

 

四、維護與保養

1. 絲杠上下兩端軸承內的潤滑脂一般3-5年更換一次。

2. 試驗機的絲杠、絲母,每半年加一次潤滑脂。

3. 保持試驗機的清潔。

五、常見故障及處理方法

1. 如在測試過程中顯示不正常或中橫梁不移動,則檢查限位是否鎖住,若限位開關鎖住,松開后重新試驗。

2. 若試驗力及位移在試驗過程中不變化,檢查連線及插座是否良好。

      3. 試驗過程中如發現異常聲音,立即停機檢查傳動系統。
