量熱儀操作步驟
熱量儀的標定
1稱樣<用坩堝稱苯甲酸1克>
2把坩堝放入氧彈，點火絲卡在氧彈上，棉線搭在點火絲上再棉線連接到煤里，加入十毫升純凈水裝好氧彈，充氧氣3Mpa<2.8---3.2之間》十五秒。
3放入機器里
4在機器上按標定鍵，輸入重量，在按標定鍵，機器自動開始工作，十五分鐘后自動打印結(jié)果。
此為機器的標定<通常機器三個月標定一次>
熱量儀的反標《也就是做苯甲酸的發(fā)熱量》
1 2 3步 同上。
4在機器上按發(fā)熱量，輸入重量，再按發(fā)熱量，機器開始工作，十五分鐘后自動打印結(jié)果。
結(jié)果出來后應與苯甲酸的實際結(jié)果對比，誤差應不超于50卡范圍
測煤的發(fā)熱量
1稱樣<用坩堝稱試驗煤0.9—1克>
2把坩堝放入氧彈，點火絲卡在氧彈上，棉線搭在點火絲上再棉線連接到煤里，加入十毫升純凈水裝好氧彈，充氧氣3Mpa十五秒。
3放入機器里
