　　Combustion method asphalt content tester features:

　　★Combustion furnace body is made of aerospace thermal insulation material,with short warm-up time and fast heating speed.It can reach the standard working temperature of 538℃in 20 minutes,which greatly saves test time compared with similar products.

　　★Good thermal insulation performance.When the inside of the furnace body reaches the standard working temperature,the outside temperature of the furnace body is lower than 45°C,and the operation safety is high.At the same time,the effect of high temperature on the accuracy of the electronic scale is effectively avoided.

　　★It has the function of secondary combustion in the post-combustion chamber,as well as high-temperature filtering and exhaust system to ensure that the test exhaust emissions meet environmental protection requirements.

　　★The instrument runs automatically and is easy to operate.Just enter the sample weight and calibration coefficient,load the sample,press the work key,and the data will be printed automatically after the test.

　　★The software is powerful and can display the asphalt content,oil-stone ratio,sample weight loss and test time at the same time.

　　★Imported balance is used to ensure accurate measurement.

　　燃烧法沥青含量测定仪操作规程：

　　★检查试验室电源是否安全接通。

　　★检查单片机电源及燃烧炉电源，接通燃烧炉电源，打开控制机箱右侧的红色开关，使单机片进入工作状态，显示屏显示工作菜单。

　　★设定温度（通常为540度），校正参数（初次校正参数为0），混和料类型。

　　★按下加热键，加热指示灯亮，燃烧炉开始加热。

　　★当炉膛达到设置温度时，打开燃烧炉炉门，此时加热自动停止，将空料筐放入托盘（请小心轻放）。

　　★关上炉门，按下加热键加热，待显示屏显示的时实温度不低于500度，试样重量数值（此时为料筐重量）稳定后（此时加热为3～10min），再按去皮键，将试样重量清0，数值应小于0.2g。（注：必须在去皮重后再打开炉门）

　　★打开炉门取出料筐，请马上关上炉门以免炉膛温度下降，将所需要试验的沥青混和料放入料筐内，注意不要堆放在一起要平摊放入料筐内。

　　★将料筐放入燃烧炉内的托盘上，一定要将料筐放置在托盘的中。才能确保试验结果的准确性。

　　★关上炉门，迅速按下加热键，加热指示灯亮，燃烧炉开始加热，显示屏显示试样重量（试验中此数值不变），加热30s后，风机开始工作，显示屏上的数值刷新一次，此时试验开始。

　　★试验中显示屏上不断的显示损失重量的数值，当损失的重量达到一定的值时，单机片自动知道试验是否结束，试验结束风机自动停止工作后，显示屏上显示试验结果，打印机自动打印试验报告。

　　★打开炉门取出料筐并清理干净，准备下次试验。

　　★如需要多份试验报告，请重复按下打印键。

　　Combustion method for asphalt content tester:

　　★Check whether the power of the laboratory is safely connected.

　　★Check the power supply of the single-chip microcomputer and the power of the combustion furnace.Turn on the power of the combustion furnace.Turn on the red switch on the right side of the control cabinet to make the single chip enter the working state.

　　★Set temperature(usually 540 degrees),calibration parameters(initial calibration parameters are 0),mix type.

　　★Press the heating key,the heating indicator lights up,and the combustion furnace starts heating.

　　★When the furnace reaches the set temperature,open the door of the combustion furnace,and the heating will automatically stop at this time.Put the empty basket into the tray(please handle it carefully).

　　★Close the furnace door,press the heating button to heat,wait until the real temperature displayed on the display is not less than 500 degrees,the sample weight value(in this case,the weight of the basket)is stable(at this time,the heating is 3 to 10 minutes),and then Press the Tare key to clear the sample weight to 0.The value should be less than 0.2g.(Note:the oven door must be opened after tare)

　　★Open the furnace door to take out the material basket.Please close the furnace door immediately to prevent the temperature of the furnace from falling.Put the asphalt mixture to be tested into the material basket.Be careful not to stack them together and put them in the material basket.

　　★Put the basket on the tray in the combustion furnace.Be sure to place the basket in the tray.In order to ensure the accuracy of the test results.

　　★Close the furnace door,quickly press the heating key,the heating indicator lights up,the combustion furnace starts heating,the display shows the sample weight(the value remains unchanged during the test),the fan starts to work after heating for 30s,and the value on the display refreshes once At this point,the test begins.

　　★During the test,the value of the weight loss is continuously displayed on the display.When the lost weight reaches a certain value,the stand-alone tablet automatically knows whether the test is over.After the test is completed,the fan automatically stops working.experiment report.

　　★Open the furnace door,take out the material basket and clean it,and prepare for the next test.

　　★If multiple test reports are required,press the print key repeatedly.
