一，產品簡介：
基于美國ASTM E1155M（地坪平整度FF和地坪水平度FL數值標準測試方法）相關要求進行研發生產，其功能和使用方法類似于美國的Dipstick測試儀或D-meter。
First, product introduction
Based on the relevant requirements of ASTM E1155M (floor flatness FF and floor level FL numerical standard test method), the function and usage method is similar to the Dipstick tester or D-meter in the United States.
二，特點：
?儀器由檢測機架和平板電腦構成，組裝維護方便；
?測試軟件為全中文，符合國人使用習慣，簡單易用；
?既可以直接讀取當前測試的地坪剖面線的平整度FF和FL值，也可以對所有測試數據進行Excel數據表存檔，便于后期分析；
?采用高精度傳感器，單組數據分辨率為0.05mm，測試精度為0.1mm 25℃）；
?全鋁合金機身，輕便易操作；
?高容量鋰電池保證持久的續航能力；
?提供配套的使用說明及數據分析教材資料。
First, the characteristics:
?The instrument consists of a test rack and a tablet computer, which is easy to assemble and maintain;
? The test software is all Chinese, in line with the habits of Chinese people, easy to use;
? It can directly read the flatness FF and FL values of the floor profile of the current test, or archive the Excel data table for all test data for later analysis;
? High-precision sensor with a single data resolution of 0.05mm and a test accuracy of 0.1mm (@25°C);
? All-aluminum body, light and easy to operate;
? High-capacity lithium battery guarantees long-lasting battery life;
? Provide supporting instructions and data analysis materials.
三，相關背景：
F數值為美國混凝土協會(AmericanConcreteInstitute#117)及加拿大標準協會(CanadianStandardAssociation#A23.1)為規范及測量混凝土地坪平整及高差的標準。此規范包括兩個F數值：FF為平整度，FL為高差值，平整度關系著地坪的隆起與凹陷；高差值關系著地坪的傾斜或高差。也就是說平整度FF表示地坪整體意義的起伏程度，水平度FL表示地坪整體意義的傾斜程度。愈高的F數值代表地坪的平整度愈佳。
econd, related background
The F values are the American Concrete Institute (American Concrete Institute #117) and the Canadian Standard Association (Canadian Standard Association #A23.1) are standards for the specification and measurement of concrete floor leveling and height difference. This specification includes two F values: FF is flatness, FL is high difference, flatness is related to the elevation and depression of the floor; high difference is related to the inclination or height difference of the floor. That is to say, the flatness FF indicates the degree of fluctuation of the overall meaning of the floor, and the level FL indicates the degree of inclination of the overall meaning of the floor. The higher the F value, the better the flatness of the floor.
