23、天平的最大稱量數(shù)，取下砝碼顯示零，則表示校正成功；若出現(xiàn)的不是最大稱量數(shù)或零，需按TAR(歸零健)歸零，再加砝碼進(jìn)行校正，重復(fù)3次。4、稱量：每次稱量，都要關(guān)閉側(cè)門、頂門。5、清零“TAR”：每稱完一個樣品都要歸零，需要盛器的樣品，稱完皮后先歸零，保證再稱的質(zhì)量為樣品質(zhì)量。注意事項：注意事項：a、本機(jī)應(yīng)置于穩(wěn)定的工作臺面上，避免震動、陽光照射和氣流。b、相對濕度應(yīng)小于75%。c、工作環(huán)境溫度1525℃，避免溫差過大。d、每次稱量時，側(cè)門
