梅特勒天平作為嘗試室經常利用根本儀器，其感化首要是稱量物體品質，想要嘗試成果加倍精確靠得住，嘗試中樣品的量必須精確。為了保障嘗試成果的精確性，必須保障梅特勒電子天平丈量的精確度，在利用前或丈量情況轉變后都要停止校準操縱。上面，咱們就來看看梅特勒電子天平若何校準。

    梅特勒電子天平有內校和外校兩種校準體例。

  1. ; 內校(xiao)(xiao)：內校(xiao)(xiao)型梅特(te)勒天(tian)平(ping)(ping)利用便利，但價錢稍高。校(xiao)(xiao)準時(shi)只(zhi)要長(chang)按CAL鍵便能(neng)夠實現校(xiao)(xiao)準進程。內校(xiao)(xiao)型電子天(tian)平(ping)(ping)如(ru)梅特(te)勒型闡發天(tian)平(ping)(ping)（AB-S/FACT系列），如(ru)圖1.

  2. 外(wai)校(xiao)(xiao)：外(wai)校(xiao)(xiao)型梅特勒天平對(dui)砝(fa)碼(ma)(ma)請求較高，砝(fa)碼(ma)(ma)有(you)塵埃、磨損時城市對(dui)校(xiao)(xiao)準(zhun)成果(guo)發(fa)生影響。校(xiao)(xiao)準(zhun)時先(xian)按CAL鍵，直到(dao)顯(xian)(xian)現(xian)(xian)(xian)(xian)屏(ping)上顯(xian)(xian)現(xian)(xian)(xian)(xian)CAL-,再(zai)把規范砝(fa)碼(ma)(ma)放(fang)入天平秤盤上，實現(xian)(xian)(xian)(xian)校(xiao)(xiao)準(zhun)進程。比方(fang)，顯(xian)(xian)現(xian)(xian)(xian)(xian)屏(ping)呈(cheng)現(xian)(xian)(xian)(xian)CAL-100時，把 100g規范砝(fa)碼(ma)(ma)放(fang)入稱盤，隨后(hou)顯(xian)(xian)現(xian)(xian)(xian)(xian)屏(ping)呈(cheng)現(xian)(xian)(xian)(xian)“----”期(qi)待(dai)狀況，當(dang)顯(xian)(xian)現(xian)(xian)(xian)(xian)屏(ping)呈(cheng)現(xian)(xian)(xian)(xian)100.000g時，取(qu)走規范砝(fa)碼(ma)(ma)，此時顯(xian)(xian)現(xian)(xian)(xian)(xian)屏(ping)應顯(xian)(xian)現(xian)(xian)(xian)(xian)0.000g,若讀數(shu) 不為零(ling)，則清零(ling)后(hou)再(zai)次停止校(xiao)(xiao)準(zhun)操縱以實現(xian)(xian)(xian)(xian)校(xiao)(xiao)準(zhun)進程。外(wai)校(xiao)(xiao)型梅特勒天平如(ru)梅特勒XP超(chao)出系列闡發(fa)天平，如(ru)圖2.

     須要注重(zhong)的(de)是，梅(mei)特(te)勒電子(zi)天(tian)平的(de)精確度(du)和內校、外校不間接的(de)干系，還應綜(zong)合斟酌別的(de)手(shou)藝(yi)目標來選購(gou)適合的(de)梅(mei)特(te)勒電子(zi)天(tian)平。
