20噸鑄造直視電子吊秤詳細信息：  

量程范圍：15t.20t.30t。  

牢固的8mm鋼板焊接外殼，防塵，防磁。  

5位數碼管顯示，字高30mm，超高亮設計。  

具有重量暫留、歸零、分度值切換等功能。 

配備高容量6v/10Ah可充電蓄電池，一次充電待機長達150小時。  

特(te)別(bie)適(shi)合大(da)噸位程金屬材料的計量，適(shi)用于(yu)物流倉庫、工(gong)礦(kuang)企業(ye)、加工(gong)車間、集(ji)貿市場、貨(huo)站(zhan)運輸等領域的進出統(tong)計,存量控制(zhi)、重(zhong)量稱重(zhong)等等。直(zhi)顯(xian)吊(diao)秤(cheng)一般具(ju)備(bei)自動累(lei)計、去(qu)(qu)皮(pi)、遠距離去(qu)(qu)皮(pi)、數值(zhi)保持(chi)、顯(xian)示分(fen)度值(zhi)、超載限制(zhi)、欠(qian)載提(ti)醒功能。  

使用免(mian)維護充電(dian)式(shi)蓄電(dian)池，當(dang)電(dian)力不足(zu)時，顯示屏(ping)會出(chu)現下列信號：  

a.低電壓指示燈(deng)亮為電力不足信號，此時應先行充(chong)電，若繼續(xu)使用，可大約使用10小(xiao)時。  

b.當電池電力(li)基本(ben)用盡，此時顯示屏關(guan)閉(bi)不顯示，請(qing)立(li)即關(guan)機充電。  

c.充電后，若顯示(shi)(shi)屏(ping)及指示(shi)(shi)燈均(jun)無法(fa)顯示(shi)(shi)，表(biao)示(shi)(shi)充電困難或電池損壞，請(qing)送經銷商進行(xing)維修。  

為(wei)延(yan)長電(dian)(dian)(dian)(dian)池壽(shou)命，請使用48小時（或1周內）后充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)一次。充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時須按充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器規(gui)格正確使用，以(yi)免(mian)損壞，另外(wai)，關閉吊(diao)秤(cheng)電(dian)(dian)(dian)(dian)源可縮短充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時間，進行充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器上的充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)指示(shi)燈會亮紅(hong)燈，表(biao)(biao)示(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)正常，待指示(shi)燈轉為(wei)綠燈時，表(biao)(biao)示(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)完(wan)成(cheng)。  

20噸鑄造直視電子吊秤計(ji)量要求(qiu)：  

A/重復性：對同一載荷，多次稱重結果(guo)之差(cha)，應不大(da)于該(gai)稱量的(de)最(zui)大(da)允許誤(wu)差(cha)的(de)絕(jue)對值(zhi)。  

B/旋轉：載荷(he)垂直起(qi)吊(diao)在水平360o；范圍(wei)內旋轉任意角度(du)示(shi)值誤差(cha)均應(ying)符合(he)規定。  

C/偏(pian)載多(duo)懸(xuan)吊點的電子(zi)吊秤應(ying)符合JJG555-1996中4.5.2的規定(ding)。  

D/多指(zhi)示(shi)(shi)裝置：電子(zi)吊秤的不同指(zhi)示(shi)(shi)裝置與打印裝置之(zhi)(zhi)間(jian)示(shi)(shi)值(zhi)之(zhi)(zhi)差應為(wei)零。  

E/誤差分配：對電子吊秤(cheng)各模(mo)塊單獨測試時，應按JJG555-1996中(zhong)4.4.4規定進行誤差分配。
