                                                                                                                          精密天平的使用方法和注意事項:
                                                                                                                         
                                                                                                                          1、先檢查并調整天平到水平位置。
                                                                                                                         
                                                                                                                          2、使用前確認電源電壓是否匹配(必要時配置穩壓器),按天平說明書的要求通電預熱到所需時間。
                                                                                                                         
                                                                                                                          3、預熱足夠時間后,開啟天平開關,會自動進行靈敏度及零點調節。等顯示穩定標志后,就可以進行正式稱量了。
                                                                                                                         
                                                                                                                          4、在稱量時,請將潔凈稱量瓶或稱量紙放在稱盤上,關閉側門,輕按去皮鍵,自動校對零點,然后逐漸加入待稱物質,直到所需重量為止。
                                                                                                                         
                                                                                                                          5、被稱物質的重量是顯示屏左下角出現“→”標志時,顯示屏所顯示的實際數值。
                                                                                                                         
                                                                                                                          6、稱量結束要及時除去稱量瓶(紙),關閉側門,電源切斷,并及時做好使用情況登記。
                                                                                                                         
                                                                                                                          7、工作臺應遠離門窗,這樣可減少因開窗開門而產生的氣流的影響;應設置在受振動干擾少的地方;應使天平遠離帶有磁性物體或其他磁場干擾。
                                                                                                                         
                                                                                                                          8、由于天平使用了高精度的電磁力平衡等傳感器與微機處理技術,請勿暴露在具有放射性或腐蝕性物質的環境中,造成天平損壞。
                                                                                                                         
                                                                                                                          9、工作室應保持清潔、干燥;不得長時間在高濕度或高粉塵的環境中使用天平;同時,天平應放置在避免陽光直射和遠離發熱器等易引起溫度變化的地方。
