　　★将真空毛细管粘度计用三氯乙烯等溶剂洗涤干净。如粘度计有油污，可用洗液、蒸馏水等仔细洗涤。洗涤后置烘箱中烘干或用通过棉花的热空气吹干。

　　★按本规程T0602准备沥青试样，将脱水过筛的试样仔细加热至充分流动状态。在加热时，予以适当搅拌，以保证加热均匀。然后将试样倾入另一个便于灌入毛细管的小盛样器中，数量均为50ml，并用盖盖好。

　　★将水槽加热，并调节恒温在60℃±0.1℃范围之内，温度计应预先校验。

　　★将选用的真空毛细管粘度计和试样置烘箱（135℃±5℃）中加热30min。

　　★从烘箱中取出3只毛细管粘度计,在室温条件下冷你却2min后,安装在保持试验温度的恒温水槽中,其位置应使I标线在水槽液面以下至少为20mm.。自烘箱中取出粘度计，至装好放入恒温水槽。

　　Asphalt kinematic viscometer operation steps:

　　★Evaluate the viscosity of the sample,and choose the type of vacuum capillary viscometer according to the time that the sample flows through the specified volume for more than 60s.

　　★Wash the vacuum capillary viscometer with trichloroethylene and other solvents.If the viscometer has oil stains,it can be washed carefully with lotion,distilled water,etc.After washing,dry in an oven or blow dry with hot air passing through cotton.

　　★Prepare the asphalt sample according to T0602 of this regulation,carefully heat the dehydrated and sieved sample to a fully flowing state.When heating,it should be properly stirred to ensure uniform heating.Then pour the sample into another small sample holder,which is easy to fill into the capillary,the amount is 50ml,and cover it with a cap.

　　★Heat the water tank and adjust the constant temperature within the range of 60℃±0.1℃.The thermometer should be calibrated in advance.

　　★The selected vacuum capillary viscometer and sample are heated in an oven(135℃±5℃)for 30min.

　　★Take out 3 capillary viscometers from the oven,and after cooling for 2 minutes at room temperature,install them in a constant temperature water tank to maintain the test temperature.The position of the I mark should be at least 20mm below the water level of the water tank.Take out the viscometer from the oven,put it into the thermostatic water tank after it is installed.

　　沥青运动粘度计安装：

　　1.打开包装箱，清点备品备件，注意玻璃器皿，尤其是毛细管粘度计要轻取轻放，不要硬扳或硬塞以免损坏。

　　3.将温度计，传感器插入缸盖相应的孔中。

　　4.再将机箱后面与缸盖的八芯插头座对接，传感器的三芯插头与机箱的三芯插座对接，四芯电源线与四芯航空插座对接。

　　SYD-265E asphalt kinematic viscometer installation:

　　1.Open the packing box and count the spare parts.Pay attention to the glassware,especially the capillary viscometer.Handle it gently.Do not pull or plug it hard to avoid damage.

　　2.Fasten the vertical ball on the hook of the bakelite cover,and adjust the bottom corner screw of the chassis so that the cylinder wall is parallel to the vertical line.

　　3.Insert the thermometer and sensor into the corresponding holes in the cylinder head.

　　4.Then connect the back of the case to the eight-pin plug socket of the cylinder head,the three-pin plug of the sensor to the three-pin socket of the case,and the four-pin power cord to the four-pin aviation socket.

　　沥青运动粘度计注意事项：

　　1.仪器无单独设置搅拌开关，打开控温开关，搅拌器同时开始工作。

　　4.实验环境改变或浴液更换时，需要重新自整定一次PID参数.

　　Note for asphalt kinematic viscometer:

　　1.The instrument does not have a separate stirring switch.When the temperature control switch is turned on,the stirrer starts to work at the same time.

　　2.The vertical state of the capillary viscometer can be adjusted by three small screws on the holder.

　　3.When installing the thermometer,make sure that the position of the mercury ball is close to the horizontal plane of the midpoint of the capillary viscometer.

　　4.When the experimental environment is changed or the bath liquid is changed,the PID parameters need to be self-tuned again.
