三、使用方法：
★将预先脱水的试样加热溶化，加热温度不得高于试样估计软化点90℃，时间不得多于30min，充分搅拌过筛后注入盛样皿内。其深度至少应超过预期针入度值约10mm放置于15－39℃的室温中冷却1h，冷却时应注意不应有灰尘落入。
★将盛样皿浸入盛满清水的水槽中，保温1－1.5h，水温保持25±0.5℃，水面应高于试验表面25mm以上。
★调整针入度仪，使之水平（必要时调节附加砝码的重量）用手揿下释放按钮，提起标准针针杆，使针杆顶端面与百分表接触头接触。
★盛样皿保温1－1.5h后取出并放入水温严格控制为25℃的平底保温皿中，试样表面以上的水层高度应不少于10mm，将保温皿置于针入度仪的圆形工作台上，调节工作台，使试样表面与针尖恰好接触（如调节工作台不够，可用调节螺母调节杠架与之配合），将百分表指针对零。
★将时间开关拨至试样所需的时间（5s或60s）档位上，按一下开始按钮，电磁铁吸合使标准针自由地穿入试样中，至红灯亮时（此时，表示标准针穿入试样中的时间已达5s或60s，电磁铁自动放磁弹簧将针杆固紧，使其针杆不再下落），用手按下百分表触头与标准针针外杆顶端面接触，此时百分表指针所指的数，即为试样的针入度。
★同一试样重复试验至少三次，每次穿入点的相互距离及与盛样皿边缘的距离都不得小于10mm，各次试验结果的平均值即为此试样的试验结果。
★每次试验前，都应检查并调节保温皿内的水温，试验后都应将标准针取下用浸有溶剂（汽油）的棉花或布拭净，再用棉花或布擦干。
Third, use method:

★ The pre-dehydrated sample should be heated and melted, the heating temperature should not be higher than the sample's estimated softening point by 90 ° C, and the time should not be longer than 30 minutes. Its depth should at least exceed the expected penetration value by about 10mm. It should be cooled at room temperature of 15-39 ° C for 1 hour. During cooling, care should be taken to prevent dust from falling into it.

★ Immerse the sample container in a water tank filled with fresh water, keep it warm for 1-1.5 hours, keep the water temperature at 25 ± 0.5 ℃, and the water surface should be more than 25mm above the test surface.

★ Adjust the penetrometer to make it level (adjust the weight of additional weight if necessary). Press the release button with your hａnd to lift the standard needle bar so that the top surface of the needle bar contacts the dial contact head.

★ After the sample container is kept warm for 1-1.5 hours, the supplier Hebei Dahong Experimental Instrument Co Ltd. takes it out and puts it in a flat-bottomed insulated dish whose water temperature is strictly controlled at 25 ° C. The height of the water layer above the surface of the sample should be not less than 10mm. Place the holding dish on the circular table of the penetrometer, adjust the table so that the surface of the sample just touches the tip of the needle (if the table is not adjusted, you can use the adjusting nut to adjust the lever bracket to match it). Pointer to zero.

★ Turn the time switch to the time (5s or 60s) position of the sample, press the start button, and the solenoid will pull the standard needle into the sample freely until the red light is on (at this time, Indicates that the standard needle has penetrated into the sample for 5s or 60s, and the electromagnet automatically releases the spring to tighten the needle bar so that the needle bar no longer drops), press the dial indicator contact and the standard needle The top surface of the outer rod is in contact. At this time, the number indicated by the pointer of the dial indicator is the penetration of the sample.

★ Repeat the test at least three times for the same sample, and the distance between each penetration point and the edge of the sample container shall not be less than 10mm. The average value of each test result is the test result of this sample.

★ Before each test, check and adjust the water temperature in the insulation dish. After the test, remove the standard needle and wipe it with cotton or cloth soaked with solvent (gasoline), then wipe it with cotton or cloth.

四、安装与调试
★新仪器开箱后，应按装箱单检查配件是否齐全，有无损坏。将针入度仪主机放在水平的平台上，接通电源，按住<手动>键使电磁铁吸合，将标准针的连杆插入传感器的孔内，放开<手动>键。把标准针与连杆联接即可。
★开箱后，检查是否因运输而发生故障。
★按装箱清单检查是否缺件，及时通知本公司销售部或销售商。
★将电源插上，打开电源，此时显示屏显示仪器名称后进入试验界面。
★为确保检测精度，通电15S后，按下仪器的<手动>键,此时针杆组件应能自由落下。
★调整仪器水平方法如下：转动调节支角，使水平泡中气泡处于中位置，此时，工作平面已处于水平位置。
Fourth, installation and commissioning

★ After unpacking the new instrument, check whether the accessories are complete and damaged according to the packing list. Put the main body of the penetrometer on a horizontal platform, turn on the power, hold down the key to engage the solenoid, insert the link of the standard needle into the hole of the sensor, and release the key. Just connect the standard needle to the connecting rod.

★ After unpacking, check if there is any malfunction due to transportation.

★ Check for missing parts according to the packing list, and notify the sales department or the seller of the company in time.

★ Plug in the power and turn on the power. At this time, the display shows the instrument name and enters the test interface.

★ To ensure the detection accuracy, press the key of the instrument after the power is turned on for 15 seconds. At this time, the needle bar assembly should be able to fall freely.

★ The method of adjusting the level of the instrument is as follows: Turn and adjust the supporting angle so that the bubbles in the horizontal bubble are in the middle position. At this time, the working plane is already in the horizontal position.
