一、保證電子(zi)天平的水平

當(dang)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)天(tian)(tian)(tian)平(ping)(ping)(ping)(ping)(ping)(ping)的水(shui)(shui)(shui)(shui)(shui)平(ping)(ping)(ping)(ping)(ping)(ping)泡(pao)在中心圓(yuan)圈內為(wei)水(shui)(shui)(shui)(shui)(shui)平(ping)(ping)(ping)(ping)(ping)(ping)，如(ru)(ru)果在圈外說明電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)天(tian)(tian)(tian)平(ping)(ping)(ping)(ping)(ping)(ping)已經不水(shui)(shui)(shui)(shui)(shui)平(ping)(ping)(ping)(ping)(ping)(ping)。電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)天(tian)(tian)(tian)平(ping)(ping)(ping)(ping)(ping)(ping)底部安裝有兩(liang)個(ge)水(shui)(shui)(shui)(shui)(shui)平(ping)(ping)(ping)(ping)(ping)(ping)調(diao)(diao)節腳，電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)天(tian)(tian)(tian)平(ping)(ping)(ping)(ping)(ping)(ping)操作界(jie)面會告訴用戶如(ru)(ru)何調(diao)(diao)整(zheng)水(shui)(shui)(shui)(shui)(shui)平(ping)(ping)(ping)(ping)(ping)(ping)調(diao)(diao)整(zheng)腳。當(dang)天(tian)(tian)(tian)平(ping)(ping)(ping)(ping)(ping)(ping)出(chu)現(xian)傾(qing)斜超過設定誤差時(shi)，顯示(shi)(shi)器上出(chu)現(xian)一(yi)個(ge)視覺(jue)性的警告標(biao)記，電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)模擬(ni)水(shui)(shui)(shui)(shui)(shui)平(ping)(ping)(ping)(ping)(ping)(ping)泡(pao)指(zhi)示(shi)(shi)器被(bei)激發(fa)，直觀指(zhi)導使用者如(ru)(ru)何將天(tian)(tian)(tian)平(ping)(ping)(ping)(ping)(ping)(ping)調(diao)(diao)節到水(shui)(shui)(shui)(shui)(shui)平(ping)(ping)(ping)(ping)(ping)(ping)位置。一(yi)旦電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)模擬(ni)水(shui)(shui)(shui)(shui)(shui)平(ping)(ping)(ping)(ping)(ping)(ping)泡(pao)指(zhi)示(shi)(shi)器的水(shui)(shui)(shui)(shui)(shui)泡(pao)對中，證明電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)天(tian)(tian)(tian)平(ping)(ping)(ping)(ping)(ping)(ping)水(shui)(shui)(shui)(shui)(shui)平(ping)(ping)(ping)(ping)(ping)(ping)已調(diao)(diao)整(zheng)到位。為(wei)了(le)保證電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)天(tian)(tian)(tian)平(ping)(ping)(ping)(ping)(ping)(ping)的準確，每次移動（安裝）電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)天(tian)(tian)(tian)平(ping)(ping)(ping)(ping)(ping)(ping)后，都要(yao)對電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)天(tian)(tian)(tian)平(ping)(ping)(ping)(ping)(ping)(ping)的水(shui)(shui)(shui)(shui)(shui)平(ping)(ping)(ping)(ping)(ping)(ping)進(jin)行調(diao)(diao)節，使其處于水(shui)(shui)(shui)(shui)(shui)平(ping)(ping)(ping)(ping)(ping)(ping)狀態。

二、校準電子天平

電子天平的校準(zhun)(zhun)，分外部(bu)(bu)校準(zhun)(zhun)、內(nei)部(bu)(bu)校準(zhun)(zhun)及自動校準(zhun)(zhun)等形式。

1. 外(wai)部校(xiao)準根據(ju)電(dian)子天(tian)平的類型，校(xiao)準砝碼(ma)分等(deng)級(ji)使用10g、50g、100g 和 500g, 校(xiao)準的砝碼(ma)必須(xu)同電(dian)子天(tian)平的準確度對(dui)(dui)應。對(dui)(dui)于外(wai)部校(xiao)準，用戶必須(xu)在(zai)配置(zhi)菜單中選擇“外(wai)校(xiao)"并進行相應的設置(zhi)，主(zhu)要步驟包括：

①選擇“校(xiao)準"“開始(shi)"；

②電子(zi)天(tian)平執行零點測(ce)量(liang)；

③在(zai)零(ling)點(dian)測(ce)量后，閃(shan)爍顯示(shi)推(tui)薦的校準重(zhong)量；

④將校準重(zhong)量砝(fa)碼放在秤(cheng)盤上，顯示繼續閃爍 ;

⑤當顯示停止閃爍(shuo)時，校準完(wan)成。

2. 內部校準

電子天平內置(zhi) 校準(zhun)(zhun)砝碼(ma)，實現(xian)線性校準(zhun)(zhun)，需在(zai)配置(zhi)菜單中選擇內部校準(zhun)(zhun)模式并進(jin)行(xing)相應的設置(zhi)。選擇“校準(zhun)(zhun)"“開始"，并在(zai)一(yi)段時間后完成。

3. 自(zi)動(dong)(dong)校(xiao)(xiao)準(zhun)(zhun)系列電子(zi)天平內置 2 組校(xiao)(xiao)準(zhun)(zhun)砝碼，實現(xian)全(quan)自(zi)動(dong)(dong)線性(xing)校(xiao)(xiao)準(zhun)(zhun)，需在配置菜單中(zhong)選擇(ze)自(zi)動(dong)(dong)校(xiao)(xiao)準(zhun)(zhun)模(mo)式并進(jin)行(xing)相應的設(she)置。電子(zi)天平每 24 小時(shi)內在設(she)置時(shi)間（比如 06：00：00 指(zhi)早上 6：00）進(jin)行(xing)自(zi)動(dong)(dong)校(xiao)(xiao)準(zhun)(zhun)，或者在溫度改變達所設(she)置的值(zhi)時(shi)（2℃）進(jin)行(xing)自(zi)動(dong)(dong)校(xiao)(xiao)準(zhun)(zhun)。

需要說明的是：

（1）對于時(shi)間(jian)自動(dong)校準或者時(shi)間(jian) / 溫度的(de)自動(dong)校準，天平的(de)時(shi)間(jian)與日期必須正確設置；

（2）當自(zi)動(dong)校(xiao)準(zhun)被激活(huo)時，也能(neng)隨(sui)時手動(dong)校(xiao)準(zhun)；

（3）自動校準僅(jin)在(zai)秤盤(pan)上五(wu)分(fen)鐘內無(wu)重量(liang)時進行；

（4）建(jian)議自(zi)動校準時(shi)間(jian)設置(zhi)在(zai)非工作時(shi)間(jian)（例如早(zao)上較早(zao)時(shi)候）。
