1、學習好資料歡迎下載光干涉甲烷測定器校驗方法一、環境條件檢查，查看檢定環境的溫度和濕度是否符合要求。二、查看被檢儀器的型號名稱、出廠編號填表。三、儀器的外觀與通電檢查外觀完好、結構完整、附件齊全、連接可靠、外露的工作部件均能正常工作。干涉條紋明亮清晰，沒有影響讀取示值的彎曲和傾斜。條紋在全量程范圍內移動時，沒有急跳現象，并無色的變化。轉動測微手輪，干涉條紋的移動量與測微手輪的刻度相對應。四、氣密性能檢查將被測儀器的抽出嘴用堵頭堵死，進氣嘴與壓力計膠管相連，確認補償微壓計在關閉狀態，打開液體壓力計，用壓力調壓計對測定器甲烷室氣路系統施加7KPa（714mmH2O）壓力，保持10min。讀取后5mi

2、n的壓力下降值，不超過10Pa判定為合格。五、示值誤差檢定1、首先用清潔空氣吹洗氣路，時間不少于30s。,2、將儀器對好零位，并用橡膠堵頭把儀器出氣嘴堵上再用膠管將儀器進氣嘴與帶有氣壓源的液體壓力計相連接。3、查表得出各檢定點需要加壓的水柱高度并記錄。4、打開補償微壓計閥門，完成1%CH4，3%CH4檢定點的檢定。關閉補償微壓計閥門，用水柱壓力計完成6%CH4，9%CH4檢定點的檢定。由低到高依次檢定，每點檢定三次，取三次算術平均值為測量值，用該測量值減去標準值的差作為該點基本誤差。學習好資料歡迎下載光干涉甲烷測定器校驗原始記錄型號名稱出廠編號環境溫度（）相對濕度（）外觀與通電檢查氣密性能檢查
