　　(2)避免電(dian)子吊秤受劇烈(lie)扳動和(he)碰(peng)撞

　　電(dian)子(zi)吊秤(cheng)內(nei)部許多(duo)電(dian)子(zi)元器(qi)件，如集成電(dian)路、石英晶體、傳感器(qi)、顯示器(qi)等，當電(dian)子(zi)吊秤(cheng)受到劇(ju)烈碰(peng)撞時，可能會損(sun)壞這些元器(qi)件，造成電(dian)子(zi)秤(cheng)故障，影響(xiang)準確度以(yi)致影響(xiang)正常使用(yong)，要(yao)避(bi)免秤(cheng)體和其他物品碰(peng)撞或從高(gao)空中摔下，儀表要(yao)輕拿輕放，不要(yao)隨意放置，以(yi)防不必要(yao)的損(sun)失，儀表固定在起重機上使用(yong)時要(yao)采(cai)取減振(zhen)措施，以(yi)免影響(xiang)可靠(kao)性。

　　(3)不得隨意拆卻電子吊秤上的零部件

　　在電子(zi)吊(diao)秤正常使用時，不要(yao)隨(sui)意拆卸(xie)電子(zi)秤上的零(ling)部件，更不要(yao)打開傳感器上的密封口(kou)，拆卸(xie)儀表上的集成(cheng)電路等(deng)元器件，必(bi)要(yao)的維(wei)修，必(bi)須(xu)在有(you)關技術人(ren)員(yuan)指導下或具備(bei)一(yi)定(ding)的維(wei)修知(zhi)識后進行，以防故障擴(kuo)大。

電(dian)子吊秤

科技名詞定義

中文名稱：電子吊秤

英文名稱(cheng)：electronic hoist scale

定義：能自動檢(jian)測和顯示所吊物料質(zhi)量和超載(zai)報警的裝置(zhi)。

電子吊秤的基本參數有準確(que)度等級、檢定分度值(zhi)e、zui大稱量(liang)（Max）、zui小(xiao)稱量（Min）和(he)工作級別(bie)。

檢定分(fen)度(du)值e 　　

e=d,d為實際分度值。 　　

檢定(ding)分度值e以含(han)質(zhi)量單位的下列數字之(zhi)一表示： 　　

1×10k.2×10k.5×10k(k為(wei)正整(zheng)數(shu)、負整(zheng)數(shu)或零)

稱量結果間的允許誤(wu)差 　　

不管稱(cheng)量結果(guo)如何(he)(he)變化，任何(he)(he)一次稱(cheng)量結果(guo)的(de)誤差，應不大于該稱(cheng)量的(de)zui大允許誤差。

電子吊秤的重復性 　　

對同一載(zai)荷，多次稱(cheng)重結果(guo)之(zhi)差，應不大(da)(da)于該稱(cheng)量的(de)zui大(da)(da)允許誤差的(de)值。
